Missions

In the frame of the sTREEt project (Impact of sTress on uRban trEEs and on city air quality, ANR), preparation and participation to various in-situ field campaigns aiming at assessing the impact of:
-drought on young potted plane trees (Platanus x hispanica) BVOC emissions on an urban site
- BVOC emissions on the gaseous and aerosol (SOA) composition of urban air

Activities

Laboratory preparation and test of the instruments used during the in-situ experiments (dynamic enclosure for BVOC emission sampling, PTR-MS, ACSM, 14C measurement on aerosol filters).
Participation to the in-situ field campaigns in spring and summer 2021 (Vitry-sur-Seine, France, 2 to 3 weeks each) and in summer 2022 (Parisian site to be selected, 4 to 5 weeks).
Data processing, elaboration of an experimental database in relation with the modeling teams of the project. Results diffusion (scientific publications, national and/or international workshops).
Expected date of start: 1st term 2021.

Skills

PhD in atmospheric chemistry/sciences with a strong experience in analytical work, and, if possible, in field work (good physical condition appreciated).
Excellent level of French and/or English
Autonomy, curiosity, skills in team work, good communicator.
Capacity of synthesis and editorial qualities.

Work Context

LSCE is internationally recognised for its excellence and leadership in the study of the past, present and future climates, using, both, experimental or modeling approaches.
The CAE team (Experimental Atmospheric Chemistry team) is specialised into the study of reactive gases and aerosols, and the assessment of their sources, both, natural and anthropogenic.
Available means and resources: dynamic sampling enclosure, mass spectroscopies for online measurements of COV (via PTRMS) and aerosols (via ACSM), analytical line for 14C measurement; 3 researchers and 2 engineers.

Constraints and risks

Field work may be physically demanding.
Due to the delay for getting a pass to enter onto the CEA (2 months for EU candidates, 3 months for others), the application form for CEA pass must be sent November 1st 2020 at the latest.
