GOES 3.9 µm, MODIS 3.7 µm, and POES AVHRR 3.8 µm shortwave IR images

AWIPS images of the 4-km resolution GOES-12 3.9 µm, the 1-km resolution MODIS 3.7 µm, and the 1-km resolution POES AVHRR 3.8 µm shortwave IR images (above; click image to enlarge) showed that there were a large number of fire “hot spots” (red to yellow colors) across parts of Kansas and Oklahoma on 08 April 2010. The majority of these fires appeared  to be in the Flint Hills region — likely the annual prescribed burns that cattle farmers perform in order to remove thatch and weeds that compete with the native grasses, to improve the range land grasses for livestock grazing.

===== 09 April Update =====

On the following day, MODIS true color imagery (below, viewed using Google Earth) showed that the ongoing fire activity was beginning to create extensive areas of smoke aloft from northern Oklahoma to eastern Kansas. There were also some large and very dense smoke plumes seen farther to the east, over portions of Arkansas and Missouri.

The first official GOES-15 Sounder visible image (above) became available starting at 17:30 UTC on 08 April 2010. For more details on the first GOES-15 Imager instrument visible images, see the CIMSS Satellite blog, the SSEC Spotlight, and the NOAA News pages. GOES-15 (GOES-P) is the final spacecraft in the GOES N/O/P series.

The GOES-15 will go through its post launch science test during the Summer of 2010 — the first IR images from the GOES-15 sounder are expected in late April of 2010.

Sounder images and products from the other GOES satellites can be found at the CIMSS GOES Realtime Derived Products site.
