Simulated altimetry products ocean - Sea Surface Heights - delayed-time - (monomission, along-track, level 3)
This simulated products "2020A_SSH_MAPPING_NATL60" (SWOT BOOST Data Challenge) are model-based Sea Surface Height (SSH) products and contain Sea Surface Height data simulated on 1) several along-track altimeter orbits (Jason1, Envisat, Geosat2, Topex/Poseidon interleaved and SWOT-nadir orbits - which is not currently in orbit) and 2) the large-swath of SWOT (not currently in orbit). These SSH data are interpolated onto the orbits thanks to the
SWOTSimulator package from a realistic high resolution ocean simulation.

The realistic high-resolution simulation is referenced as the NATL60-CMJ165 simulation based on the NEMO ocean model. The model has a horizontal grid spacing that ranges from 1.6 km at 26°N to 0.9 km at 65°N which allow to simulate realistic SSH scene that could be observed by SWOT.
Use: regional studies; ocean variability (mesoscale circulation), data challenge. For example, it will allow investigating the performance of mapping algorithms with recent and future altimeters constellation, and/or assessing the performances of altimetric missions not currently in orbit (like SWOT mission).
