The drought index (DI) is computed using SMOS derived root zone soil moisture (RZSM) monthly fields. The concept is to consider 13 years of SMOS data (2010-2022). The RZSM monthly mean and max over the period is iused to compute a soil water deficit to remove seasonal variability. from teh soil water deficit a soil moisture drought index is computed .The range of values for SMDI lies between -4 to +4, with -4 representing extreme dry conditions and +4 representing extreme wet conditions.

This product is established from one of the SMOS product: the optical thickness. The optical thickness or VOD is obtained directly from SMOS data by use of the multi-angular capability. For low vegetation (grass, crops,...) it is linked mainly to the water content while for forested areas it is more linked to the above ground biomass (AGB). The product is a yearly aggregation of AGB derived using different references (ESA BIOMASS CCI, Avitabile AGB estimates etc...) and is available for SMOS life time (2010 - now)

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 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 **

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 aggregation of daily maps of dielectric constant and its associated parameters over a 3 day moving window. The whole Earth's surface is covered in this 3-day product. Ascending and descending orbits are processed separately.
