Summary

Description

This dataset contains two-dimensional precipitation and surface products from the NESDIS Microwave Integrated Retrieval System (MIRS) using sensor data from the Advanced Technology Microwave Sounder (ATMS) onboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite. ATMS is a cross-track scanner with 22 channels in spectral bands from 23 GHz through 183 GHz. MIRS was developed by the NOAA/NESDIS Center for Satellite Application and Research (STAR) and is produced operationally at the NOAA/NESDIS Office of Satellite and Product Operations (OSPO). The precipitation and surface products file, or imaging (IMG) products file, contains total precipitable water (TPW), skin temperature, emissivity by channel, rain rate, cloud liquid water (CLW), rain water path (RWP), ice water path (IWP), liquid water path (LWP), sea ice concentration, snow water equivalent (SWE), snow cover extent, and surface type classification. Quality control metrics and flags defining retrieval product quality are also provided. Each product file encompasses one 32-second granule of data, corresponding to 4 scan lines of ATMS data. The products are distributed in netCDF-4 file format with metadata attributes included.
