Remote Sensing Applications Center 2222 West 2300 South Salt Lake City, UT 84119 - 2020 voice: (801) 975-3737 fax: (801) 975-3478 MODIS/VIIRS Burn Scar Data: MODIS and VIIRS burn scar data are provided at a sp atial resolution of 500 meters and attributed with the approximate day of burning on a per pixel basis (VI IRS burn scar data are oversampled from the native 750 meter resolution). These products are similar to the offi cial MODIS 500 meter burned area product (MCD45A1) , but are based on a different algorithmic approach. The algo rithm employed for this product is an automated hyb rid algorithm developed by Dr. Louis Giglio , and currently implemented as an Alpha product in the International Polar Orbiter Processing Package (IPOPP) by the NASA Direct Readout Laboratory (DRL) . Both IPOPP and the MODIS and VIIRS burn scar science processing algorithms are u tilized operationally within the direct readout pro cessing framework managed by the USDA Forest Service ActiveFire Mapping Program. The MODIS burn scar algorithm leverages as inputs d aily composite datasets derived from daily Terra an d Aqua MODIS observations. These include daily MODIS 500 m eter corrected reflectance (CREFL) composites, and daily composites of MODIS 1km active fire detection data. The algorithm conducts time series analyses on veg etation index data, derived from composited reflectance dat a, in the context of active fire detections to iden tify areas of change due to fire. The VIIRS burn scar algorithm leverages as inputs d aily composite datasets derived from daily Suomi NP P observations. These include daily 750 meter corrected reflectance (CVIIRSM) imagery, and daily 750 met er VIIRS-AF active fire detection data. The algorithm conducts time series analyses on vegetation index d ata, derived from daily reflectance data, in the context of dail y active fire detections to identify areas of chang e due to fire. Due to the data and analysis requirements associate d with the MODIS and VIIRS science processing algor ithms to yield reliable burn scar products, the burn scar da ta are not available in near real-time. Currently, MODIS and VIIRS burn scar data are compiled by the Active Fire Mapp ing Program as monthly datasets are typically avail able approximately 10 days after the beginning of each m onth. The burn scar data are provided as monthly Ge oTiff and KMZ products for the specified geographic regions. Please note that the completeness of these and othe r products provided by the Active Fire Mapping Prog ram is subject to anomalies typically associated with the acquisition of satellite direct broadcast data (i.e . temporary data outages, lack of comprehensive data coverage, etc.) . Please read the metadata associated with each of the burn scar datasets for additional product details and ca veats.
