    • VIIRS/JPSS1 Daily Gridded Day Night Band 500m Linear Lat Lon Grid Night NRT

    Metadata Updated: February 5, 2026

    The first of two Visible Infrared Imager Radiometer Suite (VIIRS) Day Night Band (DNB) based Near Real Time (NRT) datasets is a daily, top-of-atmosphere, at-sensor nighttime radiance product called VIIRS/JPSS1 Daily Gridded Day Night Band 500m Linear Lat Lon Grid Night NRT. Known by its short-name, VJ146A1_NRT, this product contains 26 Science Data Sets (SDS) that include sensor radiance, zenith and azimuth angles (at-sensor, solar, and lunar), cloud-mask flags, time, shortwave IR radiance, brightness temperatures, VIIRS quality flags, moon phase angle, and moon illumination fraction. It also provides Quality Flag (QF) information specific to the cloud-mask, VIIRS moderate-resolution bands M10, M11, M12, M13, M15, M16, and DNB.
