Burned Area Reflectance Classification (BARC) http://burnseverity.cr.usgs.gov/help.asp
Request Data "Emergency Requests" are for an immediate post-fire Burned Area Reflectance Classification (BARC) map for use by BAER teams. For US Forest Service lands, follow the FS link to the to the USFS Remote Sensing Applications Center in Utah. For other requests, please follow "Other Agencies."USFS Remote Sensing Applications CenterOther Agencies. "Extended Assessments" give a more comprehensive assessment of the impact of the fire. Delayed mortality and vegetation recovery become more evident. Ideally, the post-fire imagery is acquired at peak of green during the next growing season.

You will need to evaluate, compare and perhaps modify the results with field knowledge.
