This article provides a brief overview of the GOES Wildfire Automated Biomass Burning Algorithm (WF_ABBA) processing system. It includes examples of fire monitoring in the Western Hemisphere, as well as the diurnal and geographic distribution of fires. The article also explores the various applications of the GOES WF_ABBA fire product, such as land cover/land use change, global change, emissions, pollutant transport, and modeling. Additionally, future plans for the WF_ABBA algorithm are discussed.

The GOES Wildfire Automated Biomass Burning Algorithm • (WF_ABBA) • Automatically locates and characterizes sub-pixel fires in GOES imagery • - The WF_ABBA uses GOES visible, 3.9 µm and 10.7 µm data and ancillary data to identify and characterize sub-pixel fires. - Contextual techniques are used to locate hot pixels that are statistically different from the background and assign fire pixel categories: (processed; saturated; cloudy; and high, medium and low probability fire pixels) • - Numerical techniques are used to determine instantaneous estimates of sub-pixel fire size and average temperature for the processed fire pixel category based on the Dozier technique. • Ancillary data used to augment the GOES data in finding and characterizing fires- These data help to screen for false alarms and correct for water vapor attenuation, surface emissivity, solar reflectivity, and semi-transparent clouds. • - The AVHRR-derived Global Land Cover Characteristics (GLCC) data base is used to assign surface emissivity values and helps screen for false alarms. - The Aviation Model total column precipitable water is utilized to correct for water vapor attenuation. • WF_ABBA fire product consists of:- ASCII text files, McIDAS MD and AREA files • - Alpha-blended composite imagery (http://cimss.ssec.wisc.edu/goes/burn/wfabba.html)

GOES South American ABBA Fire Products Used in Land Use Land Cover Change, Climate Change, and Pollutant Transport Studies Universities, research institutes, and government planning agencies are using the GOES ABBA fire product as an indicator of land-use and land-cover change and carbon dynamics along the borders between Brazil, Peru, and Bolivia. Air pollution transport models and climate change modeling studies are using the GOES fire products to identify and “quantify” emissions due to biomass burning. Instruments such as EOS MOPITT are identifying enhanced pollution associated with biomass burning.
