Description

This dataset contains Level 2 (L2) AirSWOT geocoded products. Data were collected during the Delta-X Spring 2021 deployment over the Atchafalaya and Terrebonne basins of the Mississippi River Delta, Louisiana, USA from 2021-03-26 to 2021-04-18. AirSWOT is an airborne calibration and validation instrument for the Surface Water Topography Mission (SWOT) satellite. AirSWOT is capable of producing high resolution digital elevation models over land and water bodies using near-nadir wide-swath Ka-band radar interferometry to measure water-surface elevation and produce continuous gridded elevation data. AirSWOT elevation data is useful for calibrating elevation and slopes along the main channels, as well as tying observations to open ocean tidal conditions. The AirSWOT Level 2 data contains a set of GeoTIFF rasters in UTM map coordinates for each AirSWOT flight line.
