PhD position on atmospheric chemistry at CNRS (Orléans, France) - deadline 15/11/18

CNRS-ICARE develops research activities in the areas of combustion chemistry and physics, plasmas for propulsion and atmospheric chemistry and environment. The research activities of the Atmospheric Reactivity group (ARg) involved in this thesis subject mainly deals with laboratory and field studies of gas phase and heterogeneous chemical processes relevant for the troposphere.
The thesis will depend on the ED EMSTU (Ecole Doctorale Energie - Matériaux - Sciences de la Terre et de l'Univers), which brings together all the scientific activities of the field of materials and energy in the broad sense that are developed in the region Centre Val de Loire.

Local and regional air pollution by ozone and other photooxidants is a major issue for human health and environment. Urban areas are essentially concerned by anthropogenic Volatile Organic Compounds (VOCs) whose degradation in the presence of NO and NO2 generates this type of atmospheric pollution. In rural areas, biogenic VOCs are the main organic drivers and their chemical structure often bearing one or more unsaturated bonds makes them highly reactive towards ozone. Because of the present climate change and the increasing stress phenomena on plants, biogenic VOCs emissions are expected to increase in the next years. BVOC ozonolysis leads to the formation of new stable compounds, radicals and secondary organic aerosols (SOA). The detailed characterization of these products will allow evaluating the importance of these physico-chemical processes and their impacts on air quality and climate.
The proposed study thus involves rate constant measurements of a series of BVOCs and chemical mechanism development.The atmospheric oxydation chemistry will be investigated in environmental simulation chambers (ESC). Such facilities enable reproducing atmospheric conditions in which VOCs can be oxidized under low to high simulated polluted conditions. Product and SOA precursor kinetics will be determined using state-of-the-art analytical instrumentation connected to the chambers. It is planned to use two complementary ESC, one at ICARE (Orléans), the other at IMT (Douai).

Requirements:
The candidate must have a Master degree or equivalent, clearly showing an initiation to research (through a master's degree or a long-term internship in private or academic research).
He/she must not have already started a thesis and can not apply for another offer of ED EMSTU (552)
The profile of the candidate must be consistent with the description of the thesis subject. The post requires a high level of communication skills, both oral and written (French or English required) to be able to present at conferences and write articles in scientific publications.
We are looking for a PhD fellow who will be able to become fully involved with the project, with a thirst for knowledge, a certain independence of thought and strong motivation to develop skills in the field of atmospheric chemistry. In addition, the candidate must be able to work in a team on multi-disciplinary projects.
Applications must include a detailed CV and grades for the Masters 1 or 2 or the engineering degree.
The closing date for sending applications is 15/11/2018!

Your Job:

Atmospheric oxidation of organic compounds contributes to formation secondary gaseous pollutants and to formation of secondary aerosols. With this PhD work you will investigate to which degree the recently discovered group of highly oxygenated organic molecules contribute to the atmospheric secondary organic aerosol formation. Highly oxygenated organic molecules are formed fast in the gas phase by multiple intramolecular rearrangements in organic radicals. For such formation/condensation studies temperature controlled, continuously stirred flow reactors have proven to be extremely useful (Ehn et al. Nature, 2014).
Your tasks include to rebuilt and to improve our continuous stirred flow reactor (Jülich Plant Atmosphere Chamber), with features of flexible quantitatively controlled sources for organic compounds, carefully controlled inflow/outflow of gases and aerosols for detailed mass balances, and innovative light source management for control of oxidant levels and selection of different pathways within the oxidation cycle of organic compounds. In your new chamber setup you will investigate the atmospheric oxidation process of organic compounds, integrating: i) characterization of highly oxygenated organic molecules in the gas-phase. ii) determination of their vapour pressures and partitioning into the particulate phase. In your studies you will apply chemical ionization mass spectrometry (CIMS). 
The planning and execution of experiments require a high level of teamwork, because the interpretation of the complex chemical processes is only possible by involving other accompanying measurements.

Your Profile:

Master degree in physics, chemistry, environmental sciences or a related field with good final grade (German system equivalent 2.0 or better)
Knowledge about mass spectrometry and physical or analytical chemistry is advantageous 
Good skills in the spoken and written English language

 Research position for the project "Metal-Organic Complexes in Atmospheric Aerosol: formation processes, properties, and health impacts (MOCAA)" at University of Padua, Italy- deadline: 09/12/18

The project aims at investigating how organic compounds in atmospheric aerosol can coordinate with, and therefore increase the solubility of, metals in the aerosol itself or in atmospheric aqueous environments (e.g. cloud and fog droplets, or deliquescent aerosol at high relative humidity), and to study the effects of such mechanism on public health in an urban environment. The objectives will be pursued using an integrated approach combining field measurements, laboratory experiments, and toxicity tests. Aerosols from the urban area of Padova (Italy) within the Po Valley will be sampled, analysed to quantify metal-organic complexes and used in toxicity tests. Smog chambers will be used to realistically reproduce the gas-particle-droplet interaction in atmospheric conditions. Toxicity mechanisms will be investigated in vitro using human pulmonary alveolar epithelial cells on both atmospheric and synthetic aerosol to relate particle toxicity to the presence of metal-ligand complexes.

The position if for 12 months. All detail information on the position and on how to apply can be found by contacting prof. Chiara Gioriochiara.giorio@unipd.it

Research Engineer position (12 months or more): Algorithm development for the remote sensing of atmospheric aerosol using spaceborne lidar - Deadline: 10th October 2018

Place of work: LATMOS, Paris, Sorbonne Université , France
Type of contract: Non-permanent, full time (100%)
Duration of contract: 12 months with possible extension
Starting date: 1st November 2018
Salary will depend on level of experience as based on CNRS grid and will be about 2500€.

Elegibility criteria
The required research skills include:
 A PhD or master diploma in atmospheric sciences
 Good knowledge of UNIX operating system and use of programing tools (python, matlab,...)
 Good knowledge of data statistical analysis
 Experience in remote sensing data analysis (lidar or radar or radiometer/photometer) will be appreciated
 Good oral communication skills (English and/or French) will be appreciated

Detailed description of the job offer:
The Laboratoire Atmosphères, Milieux, Observations Spatiale (LATMOS) is a research unit funded by the National Center for Scientific Research (CNRS), the University of Versailles Saint-Quentin-en-Yvelines (UVSQ) and Sorbonne University (SU). It is based on 2 sites (Paris and Guyancourt) with around 150 permanent positions (scientists, engineers, technicians and administrative staff) and more than 230 people in total. The main LATMOS research themes are:
 physical and chemical processes in the Earth's atmosphere
 studying the planets and small bodies of the solar system;
 physics of the heliosphere, the exosphere of the planets, and plasmas in the solar system.

The proposed position belongs to the first research topic and it aims at improving aerosol parameter retrievals from spaceborne lidar observations to better quantify radiative forcings. In the frame of the joint NASA-CNES CALIPSO mission, after separation of aerosol andcloud layers, aerosol products are elaborated using type-related aerosol phase function value at the backscatter angle (hereafter called lidar ratio) for the extinction profile retrieval. In the
CALIOP lidar algorithms, it may be difficult in some cases to identify aerosol properties when their optical depth is small or in multi-layered systems when clouds are embedded in aerosol layers. At LATMOS the level data 1 are analyzed using additional information from the infrared radiometer and the level CALIOP operational products to derive the extinction profile. However, this algorithm is still dependent of near surface lidar ratios identified as a priori (type-depending) parameters in the operational algorithms. To further constrain the retrieval, we want to include information from the surface reflectance to directly retrieve the aerosol optical depth, using information obtained usingthe Synergized Optical depth of Aerosols (SODA) retrieval method. This method has been developed in the team to determine aerosol optical depth and lidar ratio over ocean or low level optically thick water cloud using the surface echo observations of the space lidar and radar (or microwave radiometer) onboard the A-Train (CALIPSO, CLOUDSAT). These products are included in the SODA database archived at the French CALIPSO archive center (AERIS/ICARE) in Lille. We will extend the use of this approach to the analysis of aerosol over land. Finally data analysis provided by a new spaceborne lidar ADM-AEOLUS launched in August 2018 will be considered in a last step to document the wavelength dependency of the aerosol optical properties. The main tasks entrusted to the engineer will be:
(1) to validate the SODA products for several aerosol type using selected regions and type periods using comparison with other measurements (MODIS, airborne or ground based lidar data making direct measurements of the lidar ratio)
(2) to include the new information about total aerosol optical depth and near surface lidar ratio in the analysis of the level 1 CALIOP data developed at LATMOS
(3) to extend analysis over land
(4) to prepare the validation of forthcoming EarthCARE mission by making comparison between the 532 nm CALIOP observations with the ADM-AEOLUS data at 355 nm.

Improvements and extension of the SODA algorithm are also part of the proposed work. Depending on the past experience of the candidate, additional task will be to write technical report and papers in peer reviewed scientific journals and to make presentations of the work at workshops and/or conferences. This work, supported by CNES will take place within the framework of the national project EECLAT (Expecting Earth-CARE, Learning from A-Train: http://eeclat.ipsl.jussieu.fr/).

PostDoc in atmospheric chemistry with application in chemical ionisation mass spectromtery at the the University of Gothenburg - Deadline: 30/06/2018

Our atmospheric science constellation is unique in Sweden in that it takes a molecular approach to transport and reaction processes in the atmosphere. A unifying focus is the study of aerosols, with activities ranging from fundamental studies of chemical reactions on the molecular level, to applied work including field studies of atmospheric processes, their importance to current climate and air quality research. The research contributes to developments in the fields of colloidal chemistry, nanotechnology, medicine as well as development of traffic related chemistry and sustainable development in developing countries.

Subject area description

The aim of this project is to quantify, understand and provide tools to describe atmospheric oxidation of organic compounds. This oxidation is important to understand formation of secondary organic aerosol (SOA) but also the generally production of oxygenated compounds that can effect air quality both in outdoor and indoor environments. Aerosol particles are crucial components in any evaluation process regarding air quality and climate change. SOA represents a significant fraction of the tropospheric aerosol. Still, the current level of understanding of SOA processes is remarkably low compared to other processes in aerosol science, i.e. modelled SOA based on experimental findings and existing theory does not capture the variability of observed SOA loadings and often predicts far less SOA than observed. It has been indicated that biogenic SOA can be largely affected by anthropogenic pollutants, i.e. NO2, SO2 or organic compounds e.g. aromatics and aldehydes. The effect of anthropogenic pollutants may explain part of the discrepancy between models and field observations. Specifically, this project applies high resolution mass spectroscopy techniques for detailed analysis of gas and particle phase to elucidate chemical mechanisms of importance for atmospheric SOA. A specific aim is how to link SOA mechanisms to model developments for descriptions in air quality and climate models. The experiments will primarily be conducted using our high-resolution time-of-flight chemical-ionization mass spectrometer (http://www.atmos-meas-tech.net/7/983/2014/amt-7-983-2014.html) in combination with inlets separating particle and gas phase for characterization of organic compositions.

Job assignments

Research in atmospheric chemistry using high resolution mass spectrometry with chemical ionization. The experimental studies can be carried out both in our laboratory but primarily in the field (India) to study the emissions and secondary transformation of organic compounds in outdoor environments. In addition to work in Sweden one is expected to participate in our international collaboration projects, currently via a field campaign in India winter 2018/2019. The work involves a great deal of analysis and evaluation of measurement data for the understanding and quantification of atmospheric oxidation of organic substances.

Eligibility To qualify as a postdoctoral fellow, the applicant must have completed a Swedish doctoral degree or must have a foreign degree corresponding to a Swedish doctoral degree.

Preference will be given to candidates who have been awarded the degree no more than three years before the application deadline and who have not held a post-doc position within the same or similar subject area at the University of Gothenburg for more than one year. Applicants with a degree obtained earlier than the stipulated three years may be preferred if special reasons exists. Special reasons in this context include, but are not limited to, leave due to illness and parental leave.

A requirement is experience in mass spectroscopy with atmospheric application demonstrated by international publications in peer-reviewed journals and experimental work.

Postdoc opportunity at University of Colorado, Boulder with Professor Veronica Vaida

Postdoctoral opportunities exist to investigate the unique micro-environments provided by aqueous surfaces, interfaces and micro-droplets, and how they affect organic photochemical reactions. The proposed research includes three related approaches: 

(1) fundamental laboratory experiments to probe multiphase, environmentally relevant systems using surface sensitive techniques, 

(2) environmental chamber studies where conditions approximating the atmosphere can be created, allowing for the assessment of the importance of interfacial chemical reactions in comparison to the better-studied bulk reactions in gas and aqueous phases, and 

(3) investigation of reactions confined in micro-droplets and vesicles, which will be compared with their bulk and surface counterparts.

This research has significant implications for planetary chemical processes, including on both the contemporary and prebiotic Earth. (1) The Earth’s ocean-atmosphere system, a sunlight-driven photochemical reactor, is a large and complex system, but has been altered over its existence through both natural and anthropogenic events. While gas phase chemistry has received the most attention, in this global reactor, chemistry occurs in all phases. In fact, it has long been established that heterogeneous and multiphase reactions can be extremely important for a fundamental understanding of environmental chemical reactions, which affect chemical processing, air quality, and ultimately visibility, human health, and the planet’s temperature. (2) More broadly, radiation from a planet’s host star provides energy capable of driving planetary processes, including those that increase a system’s chemical complexity. 

Starlight initiated reactions generate high-energy molecules that are precursors to metabolism as it has evolved in life on Earth. Experiments are designed to investigate the photochemical synthesis and reactivity of such model organic systems under conditions representative of exoplanet Earth analogues, as well as the effect of water on reactivity. Based on this photochemistry, potential spectroscopic probes will be designed for the identification of high energy species and consequently of potentially habitable environments.


To apply, please send a letter of interest, a full CV, and contact information for two references (one of which is the graduate advisor) to Professor Veronica Vaida, Department of Chemistry and Biochemistry, University of Colorado, Boulder, CO, 80309-0215 or email to Vaida@colorado.edu

Postdoctoral research Scientist - Department of Chemistry and Biochemistry, University of Colorado, Boulder - Deadline ASAP

Postdoctoral opportunities exists to investigate the unique micro-environments that aqueous surface, interfaces and micro-droplets provide, and how they affect organic photochemical reactions. The proposed research includes three related approach.:
(1) fundamental laboratory experiments to probe multiphase, environmentally relevant systems using surface sensitive technique,
(2) environmental chamber studies where conditions approximating the atmosphere can be created, to assess the importance of interface chemical reactions in comparison to the better-studied bulk reactions in the gas and aqueous phases,
(3) reactions confined in micro-droplets and vesicles will be investigated and compared with their bulk and surface counterparts. 

Implications of this research are to planetary chemical processes, including the contemporary and prebiotic Earth. (1) The Earth's ocean-atmosphere system, a Sunlight driven photochemical reactor, is a large and complex system, but has been altered over its existence through both natural and anthropogenic even.. In this global reactor, chemistry occurs in all phase, although gas phase chemistry has received the most attention. It has long been established, however, that heterogeneous and multiphase reactions can be extremely important fora fundamental understanding of environmental chemical reactions, which affect chemical processing, air quality, and ultimately visibility, human health, and the planet's temperature. (2) Starlight provides energy capable of driving planetary processes, which increase a system's chemical complexity. Starlight initiated reactions generate high-energy molecules that are precursors to metabolism as it has evolved in life on Earth. Experiments are designed to investigate the photochemical synthesis and reactivity of such model organic systems under conditions representative of exoplanet Earth analogues, as well as the effect of water on reactivity. Based on this photochemistry, potential spectroscopic probes will be designed for the identification of high energy species and consequently of potentially habitable environments.

Postdoctoral fellow in Atmospheric chemistry at the University of Gothenburg Deadline: 31st of May 2017

Research group : Atmospheric science, Professor Mattias Hallquist (hallq@chem.gu.se), University of Gothenburg

Specific subject description : The aim of this project is to quantify, understand and provide tools to describe atmospheric oxidation of organic compounds. This oxidation is important to understand formation of secondary organic aerosol (SOA) but also the generally production of oxygenated compounds that can effect air quality both in outdoor and indoor environments. Aerosol particles are crucial components in any evaluation process regarding air quality and climate change. SOA represents a significant fraction of the tropospheric aerosol. Still, the current level of understanding of SOA processes is remarkably low compared to other processes in aerosol science, i.e. modelled SOA based on experimental findings and existing theory does not capture the variability of observed SOA loadings and often predicts far less SOA than observed. It has been indicated that biogenic SOA can be largely affected by anthropogenic pollutants, i.e. NO2, SO2 or organic compounds e.g. aromatics and aldehydes. The effect of anthropogenic pollutants may explain part of the discrepancy between models and field observations. Specifically, this project applies high resolution mass spectroscopy techniques for detailed analysis of gas and particle phase to elucidate chemical mechanisms of importance for atmospheric SOA. A specific aim is how to link SOA mechanisms to model developments for descriptions in air quality and climate models.

The experiments will primarily be conducted using our high-resolution time-of-flight chemical-ionization mass spectrometer in combination with inlets separating particle and gas phase for characterization of organic compositions. (FIGAERO-CIMS)

Job assignments : Research in atmospheric chemistry using high resolution mass spectrometry with chemical ionization. The experimental studies can be carried out both in our laboratory but also in the field to study the emissions and secondary transformation of organic compounds in both indoor and outdoor environments. In addition to work in Sweden one is expected to participate in our international collaboration projects, currently with emphasis on India, China, Germany and the UK. The work involves a great deal of analysis and evaluation of measurement data for the understanding and quantification of atmospheric oxidation of organic substances.

Eligibility : The qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.

To qualify as a postdoctoral fellow, the applicant must have completed a doctoral degree corresponding to a Swedish doctoral degree. 
Preference will be given to candidates who have been awarded the degree no more than three years before the application deadline Applicants with a degree obtained earlier than the stipulated three years may be preferred if special reasons exists. Special reasons in this context include, but are not limited to, leave due to illness and parental leave.

A requirement is experience in mass spectroscopy with atmospheric application demonstrated by international publications in peer-reviewed journals and experimental work.
Preferences will be given to candidates that have experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS), where also previous experience on air quality studies in Beijing or Hong Kong are beneficial.

Assessment : Regulations for the evaluation of qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.

Experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS) with applications on atmospheric chemistry. Previous experience on air quality studies in Beijing or Hong Kong.

The research group : Our atmospheric science constellation is unique in Sweden in that it takes a molecular approach to transport and reaction processes in the atmosphere. A unifying focus is the study of aerosols, with activities ranging from fundamental studies of chemical reactions on the molecular level, to applied work including field studies of atmospheric processes, their importance to current climate and air quality research. The research contributes to developments in the fields of colloidal chemistry, nanotechnology, medicine as well as development of traffic related chemistry and sustainable development in developing countries.

The research group

Our atmospheric science constellation is unique in Sweden in that it takes a molecular approach to transport and reaction processes in the atmosphere. A unifying focus is the study of aerosols, with activities ranging from fundamental studies of chemical reactions on the molecular level, to applied work including field studies of atmospheric processes, their importance to current climate and air quality research. The research contributes to developments in the fields of colloidal chemistry, nanotechnology, medicine as well as development of traffic related chemistry and sustainable development in developing countries.
