SASS Twice-Daily SIR-Enhanced EASE-Grid 2.0 Radar Backscatter V001
Listed in NASA Earthdata CMR
This product contains twice-daily radar backscatter data collected at 14.6 GHz for horizontal-horizontal and vertical-vertical receive radar channels from the SeaSat-A satellite scatterometer (SASS) sensor.
Description
Data are available on the Northern Hemisphere, Southern Hemisphere, and Temperate EASE-Grid 2.0 projections as either 25 km or 3.125 km resolution grids. The data set uses the drop-in-the bucket gridding (GRD) and Scatterometer Image Reconstruction (SIR) algorithms to process the individual swath-based data into twice-daily morning and evening images.
The GRD algorithm produces SAR images (high-resolution) on a 25 km grid and the SIR algorithm produces slice and footprint images (both lower-resolution) on a 3.125 km grid, provided at 8-,16-, 32-day imaging intervals. The data coverage is global from 7 July 1978 through 10 Oct 1978.
