Data Description

    JPSS ATMS SDR Reprocessed (RPATMSSDR) - The Advanced Technology Microwave Sounder (ATMS) is a cross-track microwave sounder providing atmospheric temperature and moisture observations for weather and climate applications. Level-1b Sensor Data Records (SDRs) from ATMS are the calibrated and geolocated radiance and reflectance data produced from ATMS Raw Data Records. This data family includes reprocessed ATMS science SDRs and geolocation SDRs from Suomi NPP. The reprocessing generated consistent Level-1b SDRs using unified and consistent calibration algorithms that removed artificial jumps in data caused by operational changes, instrument anomalies, contamination from anomaly views of the environment or spacecraft, and other causes. The reprocessed SDRs were compared with and validated against other observations whenever such data were available. This data family includes two reprocessed data versions (RP1 and RP2). ATMS SDRs are used to produce atmospheric sounding Environmental Data Records (EDR). ATMS SDR data obtained from the NOAA Comprehensive Large Array-Data Stewardship System (CLASS) are distributed as aggregated 8 minute files consisting of 15 granules in the Hierarchical Data Format v.5 (HDF5) with metadata attributes included. See the 'Details - Metadata, Documentation' section below for additional information. Collection landing pages for the products included in this family can be accessed via the "Product Details" link.
