    "description": "The Advanced Scatterometer (ASCAT) real aperture radar is a C-band dual swath fan beam radar scatterometer onboard the European MetOp satellite series. The instrument measures radar backscatter at 6 azimuth angles and a diversity of incidence angles. The wide swath and frequent overflights permit the generation of a wide variety of ASCAT Image products. ASCAT Level-2 Ice Images are generated by NOAA using ASCAT L1B data from the European Organization for Meteorological Satellites (EUMETSAT). The images cover the Arctic, Antarctica, Alaska, the Ross Ice Shelf, and the Weddel Sea. These enhanced resolution images from ASCAT are created using the Scatterometer Image Reconstruction (SIR) algorithm with filtering (SIRF). Like previous fan-beam scatterometers, ASCAT collects measurements at multiple incidence angles and up to 6 azimuth angles. The effective image resolution varies depending on region and sampling conditions but is estimated to be 12-15 km in most areas. The data are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) in the netCDF-4 file format with attributes included.",
