Latest Satellite Scenes from MODIS: Fires Near Bolivia-Brazil Border
20 / 23 September 2004
Smoke from thousands of fires in South America near the border of Brazil and Bolivia blankets much of the continent in mid-September 2004. The abundance of smoke is an indication that forests are burning, and not just grasslands or existing agricultural land being prepared for a new growing season. Along the west coast of the continent, the Andes Mountains create a partial barrier to the spread of the smoke. The red dots in this image, which is a composite of observations captured by the Moderate Resolution Imaging Spectroradiometers (MODIS) on NASAs Terra and Aqua satellites on September 20, 2004, are active fire detections.

Maps with a summary of the occurence of vegetation fires in Brazil and in most of South America are prepared and released by CPTEC/INPE in the Internet soon after the overpasses of the NOAA-series meteorological satellites, whose AVHRR images are used in the detection.

Each red dot in the map shows a pixel with temperatures of some hundred degrees C, normally associated only to active fires. The table on the right side of the map shows the total number of fire pixels dectected by state and by country, with the percentage corresponding to the cloud cover in each region, where the detection of fires was precluded.
Geographical coordinateos of all vegetation fires detected in the AVHRR/NOAA images are available at CPTEC/INPE, and are distributed in near-real-time to registered users. Furhter information can be obtained with email@example.com, or in the phone number ++55(12)560-9261.
