Post doctoral position (12 months) at LSCE on trace gas and aerosol transport and emissions in the Siberian atmosphere from YAK-AEROSIB aircraft campaigns

LSCE – Laboratoire des Sciences du Climat et de l’Environnement
CEA-Orme des Merisiers,  

91191 GIF-SUR-YVETTE CEDEX
France

Overview

We are seeking applications for a 12 months (May 2013-May 2014) full time post-doctoral position. The successful applicant will join the Laboratory for Climate and Environmental Sciences (LSCE), a joint research unit of the CEA, CNRS and UVSQ in Gif sur Yvette, France, an internationally renowned institute in the field of biogeochemical cycles and climate research. The post-doctoral subject will be dedicated to better quantify and understand seasonal changes in atmospheric trace gases (CH4, CO2, CO, Ozone over Siberia, and the underpinning atmospheric dispersion, and surface flux processes. The post-doctoral candidate will have access to largely unpublished data from aircraft sampling campaigns between central and eastern Siberia, collected as part of a Russian French program called YAK-AEROSIB Airborne Extensive Regional Observations in SIBeria, https://yak-aerosib.lsce.ipsl.fr. New campaigns in Siberia are planned in 2012 and 2013, and the post doctoral position will be responsible for the coordination of these campaigns. He/ she will join a team of 20 scientist and engineers dedicated to the monitoring of greenhouse gases, including the Integrated Carbon Observing System (ICOS) research infrastructure, and regional inverse modelling.

Scientific context

With a large fraction of forest surface area (800x106 ha) and its huge stocks of carbon (~320 GtC), Siberia is a significant region in the global carbon cycle. Atmospheric measurements are particularly valuable in Siberia, because the atmosphere can integrate the signal of sources and sinks over this vast territory. Very few measurement programmes however exist over Siberia to measure greenhouse gases in the atmosphere. Large uncertainties remain on regional CO2 and CH4 fluxes. Siberian forests are currently assumed to be a sink of atmospheric CO2, although with a large uncertainty (Dolman et al., BG, 2013) due to data scarcity for atmospheric inversions. Siberia, with its large forested area and highly seasonal CO2 flux and transport, is a ‘hot-spot’ of greenhouse gas transport model uncertainties (Gurney et al. 2002) which can be approached using aircraft measurements. Siberia is also a significant source region in the global methane budget including the Western Siberia wetlands emissions and reactivation of bacterial activity through permafrost melting.  Long range transport into and from Siberia also add complexity to the determination of regional sources and sinks.

Position Summary

 

The successful candidate will develop research related to atmospheric measurements and modeling of CO2 and CH4 above Siberia, using new data collected by the YAK AEROSIB aircraft campaigns, and other programmes as well. He/she will be responsible for the coordination of field campaigns, and involved in the management of the project led by J.D. Paris.

Based on the existing and newly acquired data, the successful applicant will investigate the atmospheric impact of boreal ecosystems sources and sinks of CO2 and CH4 emissions, including boreal wildfires, and also anthropogenic emissions, using the regional atmospheric chemistry and transport model CHIMERE integrated at a resolution of 50 km over roughly half of Siberia.

 Essential Duties and Responsibilities:

·      Carry on research related to the atmospheric transport and estimation of surface fluxes of CO2 and CH4 over the territory of Siberia based on measurements and Eulerian and Lagrangian model tools available at LSCE (CHIMERE, FLEXPART)
·      Coordinate the preparation and execution of aircraft campaigns above Siberia
·      Process and quality-control CO2 and CH4 data obtained during the upcoming aircraft campaigns
·      Take part to the management of the YAK-AEROSIB Russian-French project
·      Participate to meetings and the French project CLimate IMpacts of Short-Lived pollutants In the Polar region (CLIMSLIP) for activities related to CH4 modeling.
 

Required Experience and Education

·      Experience working with atmospheric data analysis using models
·      Doctoral degree in an related environmental science field, such as atmospheric chemistry atmospheric physics, biogeochemistry, or other related field
 

Preferred Experience:

·      Data processing and field measurement work in related field of study
·      Atmospheric modeling,
·      Scientific project management
 
 Skills and Abilities:
·      Able to run a geoscientific model (unix environment, scripts) and to interpret results
·      Demonstrated ability to communicate effectively in written and oral forms
·      Self-motivated, autonomous and rigorous
·      Good interpersonal skills
·      Good command of English (required) and French language (optional)

 

Salary: commensurate with experience

 

To Apply: send CV and cover letter to Jean-Daniel Paris, jean-daniel.paris@lsce.ipsl.fr before end of February 2013.
