Five of these channels are imaging-resolution bands (I-Bands) with a resolution of 375 m, and sixteen are moderate-resolution bands (M-Bands) with a resolution of 750 m. The viewer also hosts Day Night Band (DNB) images that provide unique nighttime perspectives. CIMSS acquires the data from the Suomi-NPP and NOAA-20 polar-orbiting satellites via Direct Broadcast antennas. \u00a0As new images become available from the Visible Infrared Imaging Radiometer Suite (VIIRS), they are processed via <a rel=\"noreferrer noopener\" href=\"https:\/\/cimss.ssec.wisc.edu\/cspp\/\" target=\"_blank\">CSPP software<\/a> and presented in a thumbnail directory, usually within 60 minutes of acquisition onboard the spacecraft. The thumbnails link to high resolution full overpass images. In addition to the individual bands, the <a rel=\"noreferrer noopener\" href=\"https:\/\/cimss.ssec.wisc.edu\/viirs\/imagery-viewer\/\" target=\"_blank\">VIIRS Imagery Viewer<\/a> features multiple Level-2 products.
