Data Description

    NESDIS NPP Data Exploitation (NDE) Level 2 Products - The NPP Data Exploitation (NDE) system ingests Suomi NPP (S-NPP) sensor, temperature, environmental, intermediate and application related data records from the Joint Polar Satellite System (JPSS) to generate a set of satellite products referred to as NESDIS Unique Products (NUPs). This data family includes the Level 2 NDE NUPs derived from the Cross-track Infrared Sounder (CrIS) and Advanced Technology Microwave Sounder (ATMS) data. The Microwave Integrated Retrieval System (MIRS) ATMS precipitation and surface products, 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. The MIRS ATMS sounding (SND) products file contains temperature and water vapor profiles at 850, 900 and 950 millibars. Quality control metrics and flags defining retrieval product quality are also provided in the MIRS output. The NOAA-Unique CrIS-ATMS Processing System (NUCAPS) produces Cloud-Cleared Radiances (CCRs) from CrIS observations that are co-located with ATMS. The EDR product consists of retrieved estimates of hydrological variables including temperature, water vapor, cloud fraction and cloud top pressure, along with trace gas retrievals including ozone (O3), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), and nitric acid (HNO3), and a flag indicating the presence of dust and volcanic emissions. The NUCAPS Outgoing Longwave Radiation (OLR) product contains a single OLR for each CrIS field of view (FOV). These products are distributed in the native 32-second granularity in netCDF-4 file format with metadata attributes included.

Notes

    For the initial data ingest, there is a known problem that results in a small percentage of daily MIRS and NUCAPS granules not being archived. Because of this, the CLASS archive may yield gaps or missing granules in temporal and spatial searches for these products. This problem is expected to be corrected by June 2014. It is not possible for the data that was not archived to be retrospectively added to back-fill these missing granules.
