This dataset contains a high quality operational Environmental Data Record (EDR) of snow cover from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. This product provides both binary (snow or no-snow) and fractional snow cover for cloud-free areas during daytime. The algorithm utilizes VIIRS visible bands I1 (0.640 micron), I2 (0.865 micron), I3 (1.61 micron), I4 (3.74 micron), and I5 (11.5 micron) at a spatial resolution of 375 meters.

This Environmental Data Record (EDR) provides daytime cloud optical and microphysical properties (DCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi-NPP, NOAA-20, and NOAA-21.The EDR includes Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path. COD and CPS are retrieved simultaneously from visible and near-infrared observations. COD data is primarily retrieved from the conservative scattering channel at about 0.6 micrometer.

This dataset contains a high quality operational Environmental Data Record (EDR) of Ice Thickness and Age from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. This daily product provides estimates of sea and lake ice thickness and age for all pixels covered with ice. The current ice thickness and age design has the ability to estimate sea and lake ice thickness up to 3 meters under both clear and cloudy conditions at night. The algorithm also works during daytime though estimates are more uncertain.

This data set contains a high quality Environmental Data Record (EDR) of surface reflectance (SR) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard Suomi-NPP, NOAA-20, and NOAA-21. satellite. This EDR contains estimates of the surface reflectance for each VIIRS spectral band as it would have been measured at ground level as if there were no atmospheric scattering or absorption. It corrects for the effects of atmospheric gases, aerosols, and thin cirrus clouds. The VIIRS SR product is of direct heritage from the MODIS sensor onboard the AQUA and TERRA satellites.

This dataset provides a cloud height (top and base) Environmental Data Record (EDR) produced from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP, NOAA-20, and NOAA-21. The cloud height product contains an image with pixel values identifying the geopotential height at the top of a cloud layer. Additionally, this product includes data quality information that provides an assessment of the cloud height values for on-earth pixels. The algorithm uses VIIRS infrared bands M14 (8.5µm), M15 (11.2µm), and M16 (12.3µm).

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.
