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. 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. The algorithm utilizes VIIRS sensor data from the M14 (8.55mm), M15 (10.763mm), and M16 (12.013mm) spectral bands and provides global coverage every 12 hours. VIIRS volcanic ash data distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large Array-Data Stewardship System (CLASS) are distributed as single 86-second granules in NetCDF-4 format with metadata attributes included.
