| Processing Level | 2 |
| Start/Stop Date | 2014-Apr-12 to 2015-Dec-31 |
| Short Name | SWOT_SIMULATED_L2_KARIN_SSH_GLORYS_CALVAL_V1 |
| Description | This dataset provides simulated sea surface height data product that resembles data which will be collected by KaRIn. Swaths span 60 km on both sides of nadir with a nadir gap. Product provides sea surface height, sea surface height anomaly, wind speed, significant waveheight, on a geographically fixed, swath-aligned 2x2 km2 grid, as well as sea surface height on a 250x250 m2 native grid. SSH data produced by GLORYS were rendered from their native output format into the format prescribed in the SWOT L2 SSH PDD to aid ongoing data product development and to benefit future users of data produced during operational phases of the SWOT mission. |
