The following is a snapshot of the FIRMS Firefly data engine, which uses the MODIS Burned Area product to display which areas were burned by fire on which days of a specific month and year.  Our study area is outlined in red.  The different colors signify different days of the month that a fire burned.

The images from the MODIS Burned Area product shows northern Thailand in April 2001 and February 2006.  White areas are areas of no data, black areas are unburned, and grey areas are burned on a specific Julian day based on the data value.  Some white areas signify water bodies, both internal (lakes) and external (ocean), as Thailand's coast can be seen on the bottom left of both images.
