Retrievals of soil moisture and optical depth from CAROLS

Résumé

The aim of the SMOS mission is to improve our understanding of the Earth's water cycle by making global observations of soil moisture over land and salinity over oceans. Over the land surfaces, the principle of the SMOS Level 2 retrieval algorithm is to exploit multi-angular data in order to retrieve simultaneously several surface parameters including surface soil moisture and vegetation characteristics. The L-MEB (L-band Microwave Emission of the Biosphere) forward model was selected to simulate the microwave signatures of the various soil and vegetation types which are present in the mixed SMOS pixel, which is larger than about 30 × 30 km generally. The CAROLS (Combined Airborne Radio-instruments for Ocean and Land Studies) campaigns were carried out in 2007–2010 in the context of the validation of the SMOS measurements and products (mainly soil moisture and optical depth over the land surfaces). The CAROLS L-band radiometer was implemented on board the French research airplane ATR42. Over terrestrial ecosystems, the measurements were made over the south western region of France (Smosmania site and Les Landes forest) and over the VAS site (Smos validation site south-west of Valencia).
