From: The Use of Fire in the Cerrado and Amazonian Rainforests of Brazil: Past and Present
A = number of fire spots detected by satellite images and registered by INPE (Instituto National de Pesquisas Espaciais, São Paulo, Brazil) in the Amazon forest and cerrado from January to August of 2000 to 2010; B = the same number of fire spots normalized by the respective areas of the Amazon forest and cerrado (Amazon area = 419.6943 million ha; cerrado area = 203.6448 million ha, according to the Instituto Brasileiro de Geografia e Estatística-IBGE, http://www.ibge.gov.br). Numbers of fire spots come from all the satellites with optic sensors that operate in the medium-thermal band of 4 µm received by INPE, including series NOAA-AVHRR, series MODIS-TERRA, series MODIS-AQUA, GOES-10 and GOES-12, and MSG-2, at morning, afternoon, night, and dawn (http://www.dpi.inpe.br/proarco/bdqueimadas/). The values from 2007 onwards may be somewhat underestimated because NOAA-12 was decommissioned that year.
