Résumé
This study is conducted in the framework of the NASA
SMAP mission. The frozen soil mapping would certainly be
improved by using the future NASA SMAP instruments
which include both a Radiometer and a SAR operating at Lband.
SMAP will have the ability to sense the soil
conditions through moderate land cover. The radiometric
accuracy, the better spatial resolution 40 km passive and 3
km active, and the global coverage of SMAP will make
possible the monitoring of the seasonal F/T cycle at a
regional scale. The objective of this study is to develop
algorithms to track the seasonally F/T over the Tundra and
the Boreal Forest. The experimental site is located in
Northern Quebec (Nunavik) in Canada. We use available
SMOS data from Environment Canada and in situ
temperature and soil moisture data measured in different
environments of the tundra and taiga.
