An AWIPS image of Suomi NPP VIIRS 0.7 µm Day/Night Band (DNB) data (above) revealed the bright signature of the Aurora Borealis along the US/Canadian border region at 07:33 UTC (1:33/2:33 AM local time) on 15 July 2012 (NOAA Space Weather... Read More

A comparison of AWIPS images of 375-meter resolution (projected onto a 1-km AWIPS grid) Suomi NPP VIIRS 11.45 µm IR channel data with the corresponding 0.7 µm VIIRS Day/Night Band (above) showed a large Mesocale Convective System (MCS) with an expansive cold cloud shield (exihibiting IR brightness temperatures as cold...

A comparison of AWIPS images of the Suomi NPP VIIRS 0.7 µm Day/Night Band (DNB) with the corresponding 3.74 µm shortwave IR data (above) showed a large arc-shaped layer of dense smoke aloft over much of central South Dakota at 09:21 UTC (4:21 AM local time) on Read More

A comparison of AWIPS images of Suomi NPP VIIRS 11.45 µm IR, 0.7 µm Day/Night Band, and 3.74 µm shortwave IR data (above) showed (1) a pair of strong thunderstorms over the Montana/North Dakota/South Dakota border region, with cold cloud top IR brightness temperatures and excellent illumination of the overshooting...
