Experimental products including CFOSat Topography for wave current interactions studies

3 datasets are proposed 1/ along-track L3 across-track geostrophic velocities (from sea level anomaly and absolute dynamic topography) filtered at 15 and 60 km, with angle values (giving the positive across-track direction) of CFOSat mission, 2/ gridded L4 sea level anomalies and geostrophic velocities from 8 merged missions including CFOSat (Sentinel-6, Jason-3, Sentinel-3A, Sentinel-3B, Altika, Cryosat, HY2B, CFOSat) 3/ gridded L4 Sea level anomalies and geostrophic velocities from 7 merged missions without CFOsat (Sentinel-6, Jason-3, Sentinel-3A, Sentinel-3B, Altika, Cryosat, HY2B). Sea level measurements from CFOsat used for computing L3 and L4 products were retrieved using the latest version of CFOsat processing. For the L4 products, the geostrophic current is derivated from sea level anomaly maps generated with MIOST multiscale and multivariate mapping tool (Ballarotta et al., 2023, https://doi.org/10.5194/essd-15-295-2023) with level 3 altimetric data distributed by the EU Copernicus Marine Service (product SEALEVEL_GLO_PHY_L3_MY_008_062, https://doi.org/10.48670/moi-00146).
