[Met-jobs] Vacancy: Implementation of a global land data assimilation system (LDAS-Monde)

From CALVET Jean-christophe <>

Date Tue, 22 Aug 2017 15:07:58 +0200 (CEST)

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

Applications are invited for two postdoctoral research fellowships starting in 
1st quarter of 2018, at Météo-France, in the Mesoscale Modelling Group of 
Centre National de Recherches Météorologiques (CNRM) in Toulouse, France 
( to work on the following subject:

Implementation of a global land data assimilation system (LDAS-Monde)
(renewable 12-month contracts)

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) are integrated into the ISBA land surface model.
The post-doctorate fellows will contribute to the upgrade of LDAS-Monde. In 
particular, a 1D demonstrator of the Ensemble Kalman filter will be tested 2D. 
The impact of using the EnKF on land variables and on the river discharge will 
be assessed. A reanalysis of land essential climate variables (ECVs) will be 
produced and assessed. Finally, the operation of LDAS-Monde in near-real-time 
will be tested. The potential impact of the analysis on applications in 
hydrology, agrometeorology, and on the quality control of satellite-derived 
land variables will be assessed.

The net monthly salary will vary from about 2600 € to 3200 € before income tax, 
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:

The closing date for applications is *** 30 September 2017 ***.

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.
