SWOT Level 2 Water Mask Raster Image Data Product, Version 1.1
(SWOT_L2_HR_Raster_1.1)| DOI | 10.5067/SWOT-RASTER-1.1 |
| Short Name | SWOT_L2_HR_Raster_1.1 |
| Description | Rasterized water surface elevation and inundation extent in geographically fixed tiles at resolutions of 100 m and 250 m in a Universal Transverse Mercator projection grid. Provides rasters with water surface elevation, area, water fraction, backscatter, geophysical information. On-demand processing available to users for different resolutions, sampling grids, scene sizes, and file formats. Gridded scene (approx 128x128 km2, georeferenced); full swath. Available in netCDF-4 file format. |
| Version | 1.1 |
| Dataset Type | DEPRECATED |
