Relevance to SPoRT• 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) Suomi NPP

– 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)
– Superior spatially• No gaps, even at equator • Swath width: 3000km vs 2330km

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
