Texas Panhandle Fires: 12-16 March 2006

BACKGROUND

Extremely dry soil, combined with periodic episodes of strong winds, unseasonable warmth, and very low relative humidity have lead to the high risk of wild-fires across portions of the Southern Plains from late December 2005 through mid March 2006.  Very large fires in the Texas Panhandle ignited on 12 March 2006, causing loss of property and life.  This web site presents 1) maps of fire locations estimated from GOES satellite imagery, and 2) high resolution animations of visible and 3.9 micron imagery during the afternoon of 12 March. 

Fire locations are from the GOES Automated Biomass Burning Algorithm (ABBA) produced at the Cooperative Instutute of Meteorological Satellite Studies (CIMSS), University of Wisconsin-Madison.  They are accumulated hourly and daily for display at the NOAA/SPC.  For purposes of this study, fire locations have been accumulated over a period of days to compare with surface vegetation conditions, soil moisture, and population maps.

In addition, strong southwesterly surface winds behind a dryline on 30 March 2006 (two weeks after the fires) appear to have transported surface debris from the fire scars in the form of dust or ash plumes into Oklahoma.  These plumes appear to be darker than dust plumes normally observed in west Texas.  Clouds appeared to form within the plumes just west of the dryline in Oklahoma and these clouds may have had a subsequent influence on the organization of ongoing storms to the east, see Movie 3 (from Scott Bachmeier, CIMSS).

Java based applications used for interactive animations were developed by Tom Whittaker of the Space Science and Engineering Center  SSEC, University of Wisconsin-Madison.  The animations can take a while to load, depending on network speed, computer systems, etc. Also, there can be a problem viewing these on certain machines (Macs).

 


Movie 1. Fire locations 11-16 March 2006 with overlays of NDVI.




Movie 2.  Visible and 3.9 micron imagery 12 March 2006. 

Dark pixels in the 3.9 micron images indicate very high brightness temperature.  These are likely the result of wildfires within at least a fraction of the pixel.   In a few cases, these pixels appear white due to saturation of the radiometer.

Movie 3.  Visible imagery (GOES-12) 30 March 2006.

Note the dark plumes which eminate from the burn scars in west Texas.
