Any geometric correction derived by usage of terrain model isn't applied to this product by default GTC (Level 1D, Geocoded Terrain Corrected): Focused data, fully calibrated with the usage of terrain model, amplitude detected, optionally despeckled by multi-looking approach, geolocated on a DEM and represented in a uniform preselected cartographic presentation. The image scene is located and accurately rectified onto a map projection, through the use of Ground Control Points (GCPs) and Digital Elevation Model (DEM); it differs from GEC for the use of the DEM (instead of reference ellipsoid) for the accurate conversion from slant to ground range and to approximate the real earth surface. The list of available data can be retrieved using the CLEOS COSMO-SkyMed products catalogue. User registration is required to use the catalogue. As per ESA policy, very high-resolution data over conflict areas cannot be provided.

    COSMO-SkyMed ESA archive

    The COSMO-SkyMed archive collection consists of COSMO-SkyMed products requested by ESA supported projects over their areas of interest around the world. The dataset regularly grows as ESA collects new products over the years. The following list delineates the characteristics of the SAR measurement modes that are disseminated under ESA Third Party Missions (TPM). STRIPMAP HIMAGE (HIM): Achieving medium resolution (3 m x 3 m single look), wide swath imaging (swath extension ≥40 km). STRIPMAP PINGPONG (SPP): Achieving medium resolution (15 m), medium swath imaging (swath ≥30 km) with two radar polarization's selectable among HH, HV, VH and VV. SCANSAR WIDE (SCW): Achieving radar imaging with swath extension of 100 x 100 km2 and a spatial resolution of 30 x 30 m2. SCANSAR HUGE (SCH): Achieving radar imaging with swath extension of 200 x 200 km2 and a spatial resolution selectable of 100 x 100 m2. Processing Levels: Level 1A - Single-look Complex Slant - (SCSB and SCSU): RAW data focused in slant range-azimuth projection, that is the sensor natural acquisition projection; product contains In-Phase and Quadrature of the focused data, weighted and radiometrically equalised.The processing of the 1A_SCSU product differs from that of the 1A_SCSB product for the following features:a non-weighted processing is performed, which means that windowing isn't applied on the processed bandwidth; radiometric equalisation (in terms of compensation of the range antenna pattern and incidence angle) is not performed; hence only compensation of the antenna transmitter gain and receiver attenuation and range spreading loss is applied. Level 1B - Detected Ground Multi-look (DGM): Product obtained detecting, multi-looking and projecting the Single-look Complex Slant data onto a grid regular in ground. Spotlight Mode products are not multi-looked. Level 1C - Geocoded Ellipsoid Corrected (GEC) and Level 1D - Geocoded Terrain Corrected (GTC): Obtained projecting the Level 1A product onto a regular grid in a chosen cartographic reference system. In case of Lev 1C the surface is the earth ellipsoid while for the Lev 1D a DEM (Digital Elevation Model) is used to approximate the real earth surface. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service. As per ESA policy, very high-resolution data over conflict areas cannot be provided.

    SMOS L3 Daily Wind Speed

    SMOS L3WS products are daily composite maps of the collected SMOS L2 swath wind products for a specific day, provided with the same grid than the Level 2 wind data (SMOS L2WS NRT) but separated into ascending and descending passes. This product is available the day after sensing from Ifremer, in NetCDF format. Before using this dataset, please check the read-me-first note available in the Resources section below.

    SMOS NRT L2 Swath Wind Speed

    SMOS retrieved surface wind speed gridded maps (with a spatial sampling of 1/4 x 1/4 degrees) are available in NetCDF format. Each product contains parts of ascending and descending orbits and it is generated by Ifremer, starting from the SMOS L1B data products, in Near Real Time i.e. within 4 to 6 hours from sensing time. Before using this dataset, please check the read-me-first note available in the Resources section below.

    SMOS Tropical Cyclone Wind Radii Fixes

    The SMOS WRF product is available in Near Real Time to support tropical cyclones (TC) forecasts. It is generated within 4 to 6 hours from sensing from the SMOS L2 swath wind speed products, in the so-called "Fix (F-deck)" format compatible with the US Navy's ATCF (Automated Tropical Cyclone Forecasting) System. The SMOS WRF "fixes" to the best-track forecasts contain: the SMOS 10-min maximum-sustained winds (in knots) and wind radii (in nautical miles) for the 34 kt (17 m/s), 50 kt (25 m/s) and 64 kt (33 m/s) winds per geographical storm quadrants, and for each SMOS pass intercepting a TC in all the active ocean basins.
