Post-doctoral fellowship at CNRM (UMR 3589  METEO-FRANCE, CNRS)

Applications are invited for one post- doctoral research fellowship starting in September 2020, at Météo-France, in the Mesoscale Modelling Group of Centre National de Recherches

Météorologiques (CNRM) in Toulouse, France (http://www.umr-cnrm.fr/) to work on the following subject:

Evolution of a global land data assimilation system

(LDAS-Monde)

(8.5-month contract)

CNRM develops the ISBA land surface model within SURFEX, an operational modeling platform able to simulate the terrestrial water and carbon fluxes.

SURFEX is coupled to a number of atmospheric and hydrological models, and includes a land data assimilation system (LDAS) based on an Extended Kalman filter, able to analyze soil moisture and vegetation biomass at spatial resolutions ranging from 1 to 50 km.

LDAS-Monde is operational at a global scale and satellite-derived products (soil moisture, LAI, snow fractional coverage) are integrated into the ISBA land surface model.

The post-doctorate fellow will contribute to the upgrade of LDAS-Monde. In particular, the assimilation of the snow fractional

coverage will be combined with the passive monitoring of land surface temperature.

Special attention will be given to permafrost areas. The consistency these variables with other terrestrial ECVs will be made using a cross-cutting quality monitoring technique.

The reanalysis produced by LDAS-Monde will account for the synergies of the various upstream products and will provide statistics that will be used to monitor the quality of the assimilated observations.

The gross annual salary will vary from about 39000 € to 46000 €, depending on qualification.

Application should be done by email by sending a resume, a motivation letter, and the names, telephone and email address of two referees to:

[email protected] The closing date for applications is

13 May 2020.

The candidates should have knowledge on data assimilation and possibly land surface modelling and/or remote sensing of continental surfaces. They should be familiar with programming data analysis in Python, with the Linux environment, and with the FORTRAN programming language.

Funding source: Météo-France.
