“…We analyzed peat fire occurrence in Borneo based on a fire hotspot database, spanning from January 1, 1997, to August 31, 2009, (21). As there is not a single sensor system which covers the full time period, a separate analysis for 2 investigation periods was carried out: (a) from 1997 to 2000 using fire hotspots from the Advanced Very High Resolution Radiometer (AVHRR) on board the National Oceanic and Atmospheric Administration (NOAA) satellite and from the Along-Track Scanning Radiometer (ATSR) on board the European Remote Sensing Satellite 2 (ERS-2), and (b) and from 2001 to 2009 using fire hotspots from the MODerate resolution Imaging Spectroradiometer (MODIS) on board the Terra and Aqua satellites (21,22). This fire hotspot time series showed that the peat fires in 2006 were the most severe after the well known 1997-1998 fire disaster.…”
