    "title": "NOAA JPSS Visible Infrared Imaging Radiometer Suite (VIIRS) Aerosol Optical Depth and Aerosol Particle Size Distribution Environmental Data Record (EDR) from NDE",
    "description": "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. The spatial resolution is 750 meters at nadir and the temporal resolution is daily except under cloudy or unfavorable conditions. VIIRS AOD data is distributed by the Comprehensive Large-Array Stewardship System (CLASS) as single 86-second granules in the NetCDF-4 format with metadata attributes included. Note: the Aerosol Particle Size Parameter (APSP) is included only over ocean and is reported as \u00c5ngstr\u00f6m exponent.",
