The soil moisture maps provide an overview of the average weekly soil moisture retrieved from SMOS level 1 brightness temperature. The maps are derived from the level 2 SM products and are computed for ascending and descending passes. The level 1 measurements contaminated by the RFI are filtered out by the level 2 processor. For that reason the data coverage can be impacted in the area affected by permanent RFI sources. The soil moisture retrieval is also impacted by frozen / thawing soil therefore the global coverage of soil moisture data has a seasonal evolution as shown in the maps. The maps are generated for quality control purposes mainly to check the data coverage and the long term soil moisture value consistency.

The sea surface salinity maps provide an overview of the average weekly sea surface salinity retrieved from SMOS level 1 brightness temperature. The maps are derived from the level 2 OS products and are computed for ascending and descending passes. The level 1 measurements contaminated by the RFI, and instrument anomalies are filtered out by the level 2 processor. The maps show only data retrieved with good quality for the Sea Surface Salinity (SSS) retrieved with and without Land-Sea Contamination (LSC) correction and SSS anomaly based on SMOS SSS climatology. The maps are generated for quality control purposes mainly to check the data coverage and the long term sea surface salinity values consistency.

The brightness temperature maps for Land surface provide an overview of the average weekly signal sensed by SMOS. The maps are derived from the level 1 browse products and are computed for selected Stokes parameters at ascending and descending passes. The data in the maps are not filtered by RFI and other anomalies therefore strong signal corruption can be observed for some period, in some region over the Earth surface. The maps are generated for quality control purposes mainly to check the data coverage and the long term brightness temperature value consistency.
