The open position is to work on the implementation of a merged surface albedo product from the Landsat-8
and Sentinel-2 missions to ultimately achieve high temporal coverage (~less than 5 days repeat cycle) at high
spatial resolution (30m). The goal is to achieve a seamless and consistent stream of surface albedo product
(both in narrow and broadband spectral ranges) from the different sensors. Cross-calibration, atmospheric
corrections, spectral and BRDF adjustments and gridding will be taken into account.
The focus will be the innovative Sentinel-2 program that includes 2 satellites S2A & S2B to ensure a global
coverage every 5 days. S2A images of Level 2 A (ortho-rectified, atmospherically corrected with information
on cloud screening and cloud shadows) are now being distributed by CNES. This integrates the atmospheric
correction developed at CESBIO with the last version of code MACCS. A BRDF correction is operated in
rugged terrain imagery. The approach will combine the inversion of a BRDF kernel-driven model associated
with LUTs issued from a detailed radiative transfer model for vegetation canopies. The validation will carry
on the phenology and cross-comparison with ground stations with emphasis on radiative forcing estimates.
The work is achieved in the frame of the CES (Centre d'Expertise Scientifique) Albedo which is connected to
the Data Center for the surface THEIA (http://www.theia-land.fr/). It will be conducted in partnership with
CESBIO and INRA.
The candidate will be based at Centre National de Recherches Météorologiques (Toulouse, France). She/he
should have a good knowledge of the language programming (Fortran, C, C++, PYTHON) and should have
notions of graphic software (PVWave, IDL, Matlab). It is required to have a good background in remote
sensing science, surface and aerosol radiative transfer.
The position is opening for post-doctoral. Researchers that intend to expand their scientific background in
order to further postulate to French national competitions are encouraged to apply. A selection of the
candidatures is performed as they are received.
The open position is to start by March 1st 2017. Application should be done by email by sending a resume
with the list of publications, a letter of motivation, and at least two letters of reference.
The net monthly salary will vary between 2,300€ and 2,800€, depending on qualification. A one year contract
is proposed, with a possible renewal on a parent project. This salary is before income tax and includes health
