CATDS-PDC L4SM RZSM - 1 day global map of root zone soil moisture values from SMOS satellite
This product is a daily product of root zone soil moisture representative of the 0-1 m depth of the soil.
The base products, for all the CATDS-PDC (Centre Aval de Traitement des Données SMOS - Production & Dissemination Center) processing chains, are the SMOS L1B products from ESA (European Space Agency).
The L4SM RZSM is the daily product of root zone soil moisture (m3/m3) representative of the 0-1 m depth of the soil. The product contains also a quality index taking into account the presence of Radio Frequency Interference (RFI), low quality of retrieval of the input surface soil moisture, and a high fraction of non-nominal surfaces.
Products from reprocessing RE07 are available for the period 01/2010 - 05/2021. Products from operational (OPER) processing are available since 06/2021. Reprocessed products and operational products are derived using the same algorithm and configuration, hence ensuring the temporal continuity.
