NASA renames NPP satellite in honor of Wisconsin’s Verner Suomi
On 24 January 2012 NASA renamed the recently-launched NPP satellite (formerly known as the NPOES Preparatory Project)Â the Suomi National Polar-orbiting Partnership (or Suomi NPP) in honor of Dr. Verner Suomi, recognized as “the father of satellite meteorology” (see: NASA News | University of Wisconsin News). A comparison of Suomi NPP 375-meter resolution VIIRS 0.640 Âµm visible channel and 11.450 Âµm IR channel images (above) showed the eye of Category 4 Tropical Cyclone Funso, which was located in the Mozambique Channel between Africa and Madagascar at 11:02 UTC on 24 January (track of Tropical Cyclone Funso).
On 25 January 2012, another Suomi NPP 375-meter resolution VIIRS 11.450 Âµm IR image (below) displayed very cold cloud top IR brightness temperatures (as low as -77Âº C) associated with a large thunderstom complex over Texas — this storm produced hail up to 1.25 inches in diameter (SPC storm reports) and heavy rainfall of up to 9.29 inches at Uhland (NWS Austin/San Antonio Texas Public Information Statement).
The corresponding 4-km resolution GOES-13 (GOES-East) 10.7 Âµm IR image (below) showed much less structure to the cloud top temperature field, with the coldest IR brightness temperature being -70Âº C.
