The SMOS Level-4 SMAP Compatible Brightness Temperatures (BT) product provides an unbiased version of the SMOS Level-3 BT with respect to the SMAP Enhanced Level-3 BT. This data set is self-sufficient but it can also be used along with the SMAP Level-3 Enhanced BT for applications for which spatial coverage and revisit frequency of the BT measurements are essentials.

This product is an intermediate product, that provides, in daily files, SSS with qualification flags (associated confidence classes) which allow selecting valid data before averaging. Ascending and descending orbits are processed separately ** This product is no longer available, see below **

This product is the daily product of soil moisture. The retrievals are based on a multi-orbit retrieval algorithm. Ascending and descending orbits are processed separately.

This product is a synthesis product of brightness temperatures for L-Band frequency. It includes all brightness temperatures acquired that very day by the SMOS satellite operating in full pol mode. Values correspond to those at the top of the atmosphere level, transformed to the ground polarisation reference frame, binned and averaged into fixed incidence angle classes. This product is available on each of the EASE2 grid projections (cylindrical and polar).

This product is the daily product of soil moisture, and contains filtered data. The retrievals are based on a multi-orbit retrieval algorithm. A detection of freeze and snow is performed and added to the flags. Ascending and descending orbits are processed separately.

This product is an aggregation of daily maps of soil moisture, over a 3 day moving window, a decade or a month. Ascending and descending orbits are processed separately.

This product is radio frequency interference (RFI) probability for each angle bin computed daily and based on a monthly moving window average. Ascending and descending orbits are processed separately, and only in full polarization. ** This product is no longer available, see below **

This product contains average 10 days & monthly salinity field based on L2P products, ascending and descending orbits being processed separately. ** This product is no longer available, see below **

This product is an intermediate product, that provides, in daily files, SSS corrected from land-sea contamination and latitudinal bias. Ascending and descending orbits are processed separately

This product contains average 10 days & monthly salinity field corrected from land-sea contamination and latitudinal bias, based on L2Q products, ascending and descending orbits being processed separately. ** This product is no longer available, see below **
