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 the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). 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. The product also includes quality information which provides support information on the quality of ice estimates. There are no direct VIIRS channels related to the algorithm which actually relies on other VIIRS products such as cloud mask, ice surface temperature, and ice surface albedo that would use some or all VIIRS channels for their retrievals. The VIIRS Ice Thickness and Age products distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in single 86-second granules in NetCDF-4 format with metadata attributes included.
