Dataset Abstract:

In southwestern Amazonia of Brazil, Bolivia and Peru, fires have already caused environmental, social and economic problems. With the future axis of integration (Avansa Brasil) implanted in the region, fire frequency will increase, if patterns in other parts of Amazonia serve as a guide. This study offers a preliminary analysis of the accuracy of fire monitoring in 2001 by GOES-8 and NOAA-12 satellites through the comparison with field data, digital imagery, and official data. The field data are from an enforcement campaign of PROARCO/IBAMA-Acre with georeferenced fire scars observed from helicopter over flights. An over flight with INPE/IBAMA continuous videography covered over 400 km2 where fire scars were counted and then extrapolated for the state. These data were also compared with official burn permits from IBAMA and IMAC, the State Environmental Agency. Abstract. This study analyzes the accuracy of fire monitoring in 2001 by GOES-8 and NOAA-12 satellites through comparison with field, videography and official data in Acre State, Brazil. For 2001, 7100 permits for deforestation were granted for Acre State. Videographic data indicate > 6800 fires before 19 September. The number of fires extrapolated from the IBAMA enforcement flights is >2700. Hot pixels for the period of July to November 2001 from AVHRR/NOAA-12 indicate 830 fires. A partial GOES-8 database for the period 15 September through 31 October reported 1700 processed fire pixels. For the burning season of 2001, hot pixels from NOAA-12 and the GOES-8 partial data set are 9 to 2 times fewer than fires associated with burning permits, respectively. As the true number of fires is likely to be larger that indicated by the permits, the uncertain of fire frequency based on pixel data is problematic for public policy decisions. Keywords: remote sensing, GOES-8, NOAA, fire detection, biomass burning, Amazon. Data Quality Statement: The Data Center has determined that this data set has missing or incomplete data, metadata, or other documentation resulting in diminished usability of this product. User beware. Known Problems: The documentation provided with this data set is in Portuguese, with only an abstract in English (provided above). However, the data files are well organized and well structured, columns are labeled and a readme file defines the columns in both English and Portuguese. Though the documentation is sparse and thereby disqualifies this data set as a candidate for the long-term archive collection at the ORNL DAAC, these data are relatively simple and may have value to the research community.
