VIIRS Activities in Support of theNOAA Satellite Proving Ground

Sixth Meeting of the Science Advisory Committee

28 February - 1 March, 2012

National Space Science and Technology Center, Huntsville, AL

transitioning unique NASA data and research technologies to operations


Relevance to sport

Relevance to SPoRT

Suomi NPP

  • Visible Infrared Imaging Radiometer Suite

  • Joint NASA/NOAA instrument

  • MODIS & AVHRR/OLS heritage

    • High-resolution; better near edge-of-swath

      • 370 m res. for Imaging bands (MODIS 250 m Visible)

      • 740 m res. for Moderate bands (MODIS 500/1000 m IR)


Viirs improved scan geometry

VIIRS Improved Scan Geometry

      • 370 m res. for Imaging bands (MODIS 250 m Visible)

      • 740 m res. for Moderate bands (MODIS 500/1000 m IR)

    • Superior spatially

      • No gaps, even at equator

      • Swath width: 3000km vs 2330km

Future work

Future Work

  • Demonstrate usefulness of VIIRS products

    • Focus on High-Latitude issues over Alaska Region

      • Include testbed cases in Southern Region

    • Resolution improvement over MODIS (full scan)

      • Add VIIRS to CONUS Hybrid

      • Create OCONUS Hybrids over AK and Pac

    • Low light channel (Day-Night-Band)

      • Clouds, Fog

      • RGBs
