This Environmental Data Record (EDR) provides volcanic ash from the Visible Infrared Imaging Radiometer (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. The EDR contains two images with pixel values identifying volcanic ash cloud height and volcanic ash mass loading. The product also includes two types of data quality information, one indicator describes the quality of the volcanic ash detection, and the second indicator provides information about the quality and ash characteristics of the retrieval for on-earth pixels.

This Environmental Data Record (EDR) provides nighttime cloud optical and microphysical properties (NCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi-NPP, NOAA-20, and NOAA-21.The EDR contains Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path. NCOMP algorithm uses VIIRS bands M7, M15, and M16 and provides daily, global coverage at a spatial resolution of 750 meters at nadir. Liquid and ice water path are calculated subsequently from COD and CPS.

This Environmental Data Record (EDR) provides suspended matter from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. satellite. 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. The dust and smoke masks indicate the presence of dust and smoke, respectively.

This Environmental Data Record (EDR) provides aerosol optical depth (AOD) and particle size from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. 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 AOD product consists of vertically-integrated total column extinction at mid-visible 0.55 micron and for a range of wavelengths from 0.412 to 2.25 micron.

This Environmental Data Record (EDR) provides Sea Ice Concentration (SIC) and Ice Surface Temperature (IST) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. 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. The product also includes quality information which provides support information on the quality of ice estimates.

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 Suomi-NPP, NOAA-20, and NOAA-21. This daily product provides global 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, NOAA-210, and NOAA-21. This daily product provides global 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, NOAA-20, and NOAA-21 satellites. 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).
