    • NSCAT Twice-Daily SIR-Enhanced EASE-Grid 2.0 Radar Backscatter V001

    Metadata Updated: August 22, 2025

    This data set provides twice-daily enhanced-resolution radar backscatter images from 14 GHz NASA Scatterometer (NSCAT) observations by applying the Scatterometer Image Reconstruction with Filtering (SIRF) algorithm. The algorithm incorporates a median filter and a simplified spatial response function. Multiple passes of the spacecraft are combined to produce a higher spatial resolution and fill in coverage gaps between the individual measurement footprints, which are not contiguous and have six-sided shapes. Overlapping imaging periods start each day and extend through 4- and 8-day periods. Data are gridded to Northern Hemisphere, Southern Hemisphere, and Temperate EASE-Grid 2.0 projections at 3.125 km and 25 km resolutions.
