Fires were burning across Brazil and Bolivia on September 23, 2003. Fire is commonly used to clear land for agriculture or to maintain pasture in the region.
Hundreds—possibly thousands—of active fire detections were made by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on August 31, 2003, across western Brazil (top right) and Bolivia (bottom left). These fires, marked with red dots, are billowing smoke which hangs over the terrain, nearly obscuring it in some places.
