Offer Description

The substantial role of the stratosphere in the Earth system and its impact on surface weather and climate are now well recognized. However, many questions remain on how the stratospheric processes and interfaces will evolve in a changing climate. The current understanding of the factors of stratospheric variability is far from being complete, which renders climate projections uncertain. Since the stratosphere has two-way interaction with the troposphere (through both mass and energy exchange) the increasingly frequent tropospheric extreme weather, such as massive wildfires, becomes an important factor of the stratosphere's variability and related effects on climate. In addition, the stratospheric system may be strongly forced by natural processes such as explosive volcanic eruptions, leading to prolonged perturbation of stratospheric composition.
The primary objective of the proposed Postdoc fellowship is characterization and quantification of the stratospheric impact by extreme events such as volcanic eruptions and intense wildfires through synergistic use of satellite and ground-based observations. An important aspect of the mission will be to actively contribute to the new web portal for NRT analysis and visualization of various types of stratospheric observations, in particular the data from ground-based and satellite LiDAR instruments.

- Synergistic analysis of satellite limb and nadir observations at the limb (such as CALIPSO, MLS, OMPS-LP, TROPOMI and others) estimation of mass fluxes in the stratosphere
- Retrieval of ERA5 weather data via the CDS API service
- Automation of processing and analysis of data obtained by ground lidars
- Contribution to the development of the new web portal for the analysis and visualization of different types of stratospheric observations
- Evaluation of results by comparison with other inventories or observations
- Presentation of results at national and international conferences
- Writing reports, abstracts and scientific articles

The work is to be carried out in LATMOS (Guyancourt) under supervision of Sergey Khaykin within the STRATO team in the frame of INSU/CNRS CPJ STANDARDS project.
LATMOS is a mixed research unit specialized in the study of the physico-chemical processes governing the terrestrial and planetary atmospheres and their interfaces with the surface, the ocean, and the interplanetary environment.The Laboratory has developed strong instrumental skills, built innovative instruments deployed from the ground and sometimes put into orbit or set off to meet other bodies in the solar system. Numerical atmospheric models are also developed and used to interpret the various observations.
