This dataset contains a high quality operational Environmental Data Record (EDR) of volcanic ash from the Visible Infrared Imaging Radiometer (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The EDR contains two images with pixel values identifying volcanic ash cloud height and volcanic ash mass loading.

This data set contains a high quality Environmental Data Record (EDR) of nighttime cloud optical and microphysical properties (NCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The EDR contains Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path (LWP and IWP). Liquid and ice water path are calculated subsequently from COD and CPS. The NCOMP algorithm uses VIIRS bands M7, M15, and M16.

This dataset contains a high quality operational Environmental Data Record (EDR) of suspended matter from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The retrieval algorithm is based on a legacy product originally developed for the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor but is adapted and improved upon for use by VIIRS. The aerosol mask indicates the presence of either smoke or dust.

This dataset contains a high quality operational Environmental Data Record (EDR) of aerosol optical depth (AOD) and particle size from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The retrieval algorithm is based on a legacy product originally developed for the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor but is adapted and improved upon for use by VIIRS.

This dataset contains a high quality operational Environmental Data Record (EDR) of Sea Ice Concentration (SIC) and Ice Surface Temperature (IST) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). This daily product identifies ice cover and estimates ice concentration and ice surface temperature over water surfaces for clear (cloud-free) pixels. No land ice applications are included.

This dataset contains a high quality operational Environmental Data Record (EDR) of nadir profiler ozone from the Ozone Mapping and Profiling Suite (OMPS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). This global daily product provides estimates of layer ozone amounts, UV reflectivity, and absorbing aerosol index values at a spatial resolution of 50 kilometers at nadir. The EDR also contains quality information including quality flags, measurement sensitivities, and retrieval efficiency factors.

This dataset contains a high quality operational Environmental Data Record (EDR) of total column ozone from the Ozone Mapping and Profiling Suite (OMPS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). This global daily product provides estimates of total column ozone, UV reflectivity, and absorbing aerosol index values at a spatial resolution of 50 kilometers at nadir. The EDR also contains quality information including quality flags, measurement sensitivities, and retrieval efficiency factors.

This dataset contains a high quality operational Environmental Data
Record (EDR) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument
onboard the Suomi-NPP, NOAA-20, and NOAA-21 satellites. The dataset is produced by
the NOAA Satellite and Information Service (NESDIS), and is an EDR of Imagery from
all 5 I-bands and 6 of the 16 M-bands. It is important to note however that only the
I-band EDR Imagery is archived in CLASS, the M-band EDR Imagery is not. The VIIRS

This global Level-1B (1b) Sensor Data Record (SDR) provides calibrated and geolocated radiance data acquired by the Ozone Mapping and Profiler Suite (OMPS) onboard the Suomi-NPP satellite. The data are derived from observations (between 290-1,000 nm) detected by the OMPS Limb Profiler (LP) with an estimated vertical resolution of 700 m at nadir. This data set is generated from the OMPS Raw Data Records (RDR) and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS).

The Advanced Technology Microwave Sounder (ATMS) is a 22 channel microwave sounder on-board the Suomi-NPP satellite. ATMS is primarily used to detect and measure atmospheric temperature and moisture profiles. This metadata record encompasses all ATMS Raw Data Records (RDRs), which include science, diagnostic and telemetry RDRs. These products are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS).
