Amazon region (Brazil), 1997-98
The following night time images are derived from the ERS ATSR nadir view
calibrated data. The RGB colour composition is made using 3.7 and 11 micro
channels. In all the images, except the first one, all pixel showing saturation
in 3.7 micron channel (temperature above 312 K (39 C) degrees) have been
superimposed on the final RGB composite as red "hot" spots.
The cold clouds
with temperatures less than 274 K (1 C) in both channels appear in black color
in the images. The warmer areas with temperature greater than 305 K (32 C) in
channel 3.7 appear as clear yellow features.
The Coastlines have been set
over images in white color to evidence Land/Sea contours.
The data are at
full resolution (1km) in satellite projection with image samples along satellite
track and image lines across satellite track.

The fires, which have raged out of control again since mid-January 1998,
cover about 22,000 square miles, an area slightly larger than Costa Rica. So
far, 12,000 head of cattle have died in Roraima. About $36 million in crops have
been destroyed; flames illuminate the night sky in Roraima, while a vast smoke
cloud, which spans more than 188 miles (300 kilometers), blots out the sun
during the day.
Strong winds continue to push the flames deeper into the villages of the
Yanomami Indians, considered the world's largest surviving Stone Age tribe. The
reservation, which has already lost about 8 square miles of forest, is home to
about 3,000 Yanomami. About a fifth of the area in flames is forest, and the
rest is pasture. Logging and slash-and-burn agriculture have combined to create
conditions ripe for the disaster, scientists say. Also, it is Brazil's worst
drought in three decades.

Strong rains fall on fire-ravaged Amazon state
March 31,
1998
The first strong rains in six months fell Tuesday on the remote Amazon
state of Roraima, kindling hopes that wildfires that have raged out of control
for three months would soon end. Newly available satellite photos show that
about 13,200 square miles (about 15 percent of the Amazon state) have been
devastated by the fires, which were set by subsistence farmers.
