    "title": "NOAA JPSS Visible Infrared Imaging Radiometer Suite (VIIRS) Volcanic Ash Detection and Height Environmental Data Record (EDR) from NDE",
    "description": "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. 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. The data are produced by NOAA's Office of Satellite and Product Operations (OSPO) and distributed by NOAA's Comprehensive Large Array-Data Stewardship System (CLASS) as 86 second granules in the netCDF-4 file format with metadata attributes included.",
