Instead, we recommend to use the updated version of the product CATDS-PDC L3TB - Global polarised brightness temperature product from SMOS satellite (https://doi.org/10.12770/6294e08c-baec-4282-a251-33fee22ec67f), which now contains a probability of RFI contamination field. 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 L3RFI 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 polarisation. Products from reprocessing RE04 are available for the period 01/2010 - 04/2015. Products from operational (OPER) processing are available since 05/2015. Reprocessed products and operational products are derived using the same algorithm and configuration, hence ensuring the temporal continuity.
