SMOS Data Products
This page provides a structured access to all available information related to the SMOS mission data products. The links in the following tables provides a quick access to the main resources.
The following SMOS data products description provides detailed information and links to exhaustive documentation: read-me-first notes, Algorithm Theoretical Baseline Documents, Product Specification Documents and Data Quality Reports. The definition of the data products is based on the the CEOS (Committee on Earth Observation Satellites) conventions.
Raw dataThese are SMOS Payload data in their original format (CCSDS packets) comprised of instrument observation data and housekeeping telemetry, as received from the satellite.
Level 0 data productsThese are SMOS payload data in so-called Source Packets with added Earth Explorer product headers. They are chronologically sorted by Source Packet type: Observation Data and Housekeeping Telemetry. Detailed description of the SMOS L0 data format is available in the Level 0 data product specifications document (PDF).
Level 1 data productsThe level 1 data products are for scientific users and are generated by the L1OP Processor integrated in the Data Processing Ground Segment. They are available in Earth Explorer format from the SMOS data portal.
For an optimal exploitation of the current SMOS L1 data set V620 consult the read-me-first note available here.
Previous level 1 data products V505 read-me-first note is available here
Level 1 Near Real Time data productsThe level 1 Near Real Time (NRT) data products are similar to the L1C product but adjusted to requirements of operational meteorological agencies. The NRT products are generated by the NRT Processor integrated in the Data Processing Ground Segment in BUFR format. NRT data is available from ESA, NRT light is available from SMOS data portal, EUMETCast Europe and WMO GTS within three hours from sensing time. For an optimal exploitation of the current SMOS L1 data set V620 consult the read-me-first note available here.
Level 2 data productsThe level 2 data products are for scientific users and are generated by the L2OP Processors integrated in the Data Processing Ground Segment. They are available in Earth Explorer format and netCDF format from the SMOS data portal. For an optimal exploitation of the current SMOS L2 data set V6 consult the read-me-first notes available for V650 soil moisture data and V662 sea surface salinity data.

Level 2 Soil Moisture Near Real Time Neural Network dataThe Soil Moisture Near Real Time Neural Network product (SM-NRT-NN) provides fast access (within four hours from sensing time) of soil moisture measurements. The soil moisture is retrieved from the multi-angular brightness temperature as available inside the SMOS level 1 Near Real Time BUFR product. The retrieval is based on a neural network schema trained using the level 2 soil moisture data set generated by the operational L2 soil moisture processor V620. The SM-NRT-NN product is avaialble from EUMETCast Europe, WMO GTS and SMOS data portal in netCDF format. For an optimal exploitation of the current SM-NRT-NN product v200 consult the read-me-first note available here.
Previous level 2 SM-NRT-NN data products v100 read-me-first note is available here. Level 3 Sea-ice productThe level 3 sea-ice product is derived from ESA L1C product. The sea-ice thickness is retrieved up to a depth of ~ 0.5-1 m, depending on the ice temperature and ice salinity. The product is complementary with sea-ice thickness measurements from ESA's CryoSat-2 and Sentinel-3 missions. Daily maps are disseminated with a latency of about 24 hours. The product is available in netCDF format from the SMOS data portal.
Level 3 and 4 data productsFor Sea Surface Salinity and Soil Moisture level 3 and 4 data products see the national French and Spanish processing entities: Centre Aval de Traitement des Données SMOS (CATDS) and SMOS CP34.
