ICARTT Analysis Products: Biomass Burning Emissions

The Center for International Disaster Information publishes daily burn areas, burnt per province in Canada and fire province in the U.S. The resulting timeseries were smoothed by a 3-day running mean. As a second source of information, MODIS hot spot data were obtained from the NOAA Satellite and Information Service. Hot spots were counted daily on a 1x1 degree grid and for every 3-day period the maximum daily number of hot spots was taken in order to account for possibly missing hot spots during cloudy periods. Then, the daily area burned in Alaska and the Canadian provinces was distributed to those grid cells in these provinces containing hot spots (weighted, according to the number of hot spots). The rest of the U.S. was treated as a single region instead of as different fire provinces. Sometimes, hot spots were detected when no area was given as burned in a province or vice versa. The missing area (about 10%) was distributed equally-weighted to all hot spots detected during the entire period. Finally, a constant emission factor of 4500 kg CO / hectare burned was used to obtain a daily CO emission inventory on a 1x1 degree grid.
