  "description": "The VIIRS/JPSS2 Day/Night Band 6-Min L1B Swath 750 m, short-name VJ202DNB, of the Joint Polar-orbiting Satellite System-2 (JPSS-2/NOAA-21; referred to hereafter as J2) platform-derived single NASA VIIRS panchromatic Day-Night band (DNB) calibrated radiance product.  The DNB is one of the M-bands with an at-nadir spatial resolution of 750 meters (across the entire scan).  The panchromatic DNB’s spectral wavelength ranges from 0.5 micrometer to 0.9 micrometer.  It facilitates measuring night lights, reflected solar/lunar lights with a large dynamic range between a low of a quarter moon illumination to the brightest daylight.  \n\nThe J2 VIIRS radiometric calibration Level-1B reprocessing includes a few calibration updates for the reflective solar bands (RSB), but no significant changes for the day-night band (DNB) or thermal emissive bands (TEB).",
