abstract = "The demand for information on fire activity in Amazonia has
significantly increased in the past two decades with the growing
concern about the fate of the tropical forests. Satellite active
fire detection products represent the primary data source of fire
information for Amazonia, which includes near-real time data from
polar orbiting instruments such as the Advanced Very High
Resolution Radiometer (AVHRR) series and the Moderate Resolution
Imaging Spectroradiometer (MODIS) aboard Terra and Aqua
satellites, and from geostationary systems such as the
Geostationary Operational Environmental Satellite (GOES) East
imager series. Airborne remote sensing instruments also provide
invaluable information over fewer opportunistic/selected fires.
Biomass burning is a major factor influencing land use and land
cover change in Amazonia, its carbon dynamics, sustainability and
system functioning, including important effects on the
hydrological cycle. Consequently, it became a hot topic within the
Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
Here we report on the summary findings about the LBA-Eco Phase III
synthesis project entitled Analysis of long-term fire dynamics and
impacts in the Amazon using integrated multi-source fire
observations (LC-35 group investigation). Using multi-source fire
data derived from in situ data collection, airborne remote
sensing, Landsat-class type imagery, and moderate-to-coarse
spatial resolution data (AVHRR, MODIS, GOES), we provide a summary
overview of fire activity in Amazonia over the past decade. We
analyzed several million fire pixels detected from 1997-present,
including detailed imaging of thousands of maintenance and
conversion fires mapped by the Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER) and Landsat Enhanced
Thematic Mapper Plus (ETM+) instruments. Our results highlight the
spatial and temporal trends in fire activity across Amazonia,
including important data quality information (e.g., omission and
commission errors affecting the near-real time MODIS and GOES
active fire detection data). We describe the relationship between
fire activity and vegetation characteristics, deforestation,
precipitation, and cloud distribution in Amazonia, which combine
to create contrasting regional fire regimes across the area.",
