Post-doctoral position in tropospheric chemistry within the IGAS project at Université Paul Sabatier, Toulouse, France

Title: validation of IASI data and characterization of the Asian UT composition with IAGOS

Duration: 12 to 18 months starting as soon as possible and before November 2013

Salary: The successful applicant will be funded by the European/FP7 project IGAS (IAGOS for GMES Atmospheric Service, www.igas-project.org ) and employed by Université Paul Sabatier (UPS), with a gross monthly salary of 2200 to 2600 Euros depending on experience (include unemployment, retirement and basic social security).

Background
:
The IGAS project deals with the use of IAGOS (
http://www.iagos.org) airborne observations in the framework of GMES/Copernicus applications and services. IAGOS O3 and CO observations taken at take-off and landing are ideal for the validation of satellite data. The first and second Metop/IASI satellite sensors have been launched in 2006 and 2012. IASI enables the retrieval of the tropospheric and UTLS content of atmospheric pollutants such as O3 and CO. The Laboratoire d'Aérologie from UPS (http://www.aero.obs-mip.fr) is involved in both the retrieval and validation of IASI chemistry data. Furthermore, the latest IAGOS data provide a unique dataset to understand the transport and chemical processes driving the composition of the upper troposphere over Asia.

Work description
:
The first task will be to set up the tools enabling the validation of IASI chemistry retrievals with IAGOS data. The work will consist in developing tools to (i) complete the partially observed IAGOS profiles and calculate partial and total columns by extending them with selected external information, such as stratospheric satellite observations, climatology or model outputs (ii) retrieve satellite data collocated with the airborne data (iii) convolve the complete profiles with the averaging kernels from IASI. The validation will then be performed including the latest IAGOS data.

The second objective of this post-doc will be to use the latest IAGOS data to better characterize the impact of Asian pollution uplift during the monsoon on the UT composition. Satellite observations have shown that during boreal summer, the uplifted pollutants are trapped within the Asian Monsoon Anticyclone. Recent O3 and CO data collected from Asia-Europe and Asia-Middle East IAGOS flights will be unique to accurately determine the chemical edge of the Asian Monsoon Anticyclone and to help quantify the O3 budget in the Anticyclone. IAGOS data may be complemented with satellite data (IASI), lagrangian (FLEXPART) and chemistry transport (GEOS-Chem) modelisation tools.

The successful candidate will work within the “Ozone and precursors” team of Laboratoire d’Aérologie.
The candidate will be responsible for his WP deliverables and will participate to the IGAS meetings and collaborate with the colleagues involved in this WP (KNMI, MPI-Jena). Good skills in computer programming (Fortran, IDL/NCL/Matlab and possibly Python) are required. A recent Ph.D. graduate with knowledge in atmospheric sciences, and/or remote sensing is desirable. Correct English (spoken and written) is required and French speaking would be positive.

Applications including
:
- a cover letter
- a complete CV
- the names (plus full address and e-mail) of two referees
- eventually recommendation letters
should be sent preferably by e-mail to Brice Barret (brice.barret@aero.obs-mip.fr).
