Take over Siberia, Russia, this image is created by adding the visible band and thermal band. the visible band shows the smoke and the burn area caused by fires. Infrared bands show the active fire itself.

A similar image of Kolymskya Nizmenost, southern Russia. It clearly shows the forest fires and their burnt scar. this image was taken in different time of the day than the previous one.

An infrared image  Cyprus Island, in the Mediterranean Sea. It shows an active fire burning in the southern part. Notice, AVHRR's advantageous high spatial  resolution.

The image is a false color composite of visible channel data. It clearly shows the plume of smoke emanating from fires in Borneo Island, Indonesia.

This is a color composite image of the forest fires presently raging in the States of Idaho and Montana. In this representation there is a clear distinction between the cloud (white) and the smoke from the fires (blue), whilst forested areas appear green.

This is a night-time false color image, showing the coast of Turkey and some of the Greek Islands. A cloud of warm smoke, due to wild fires, is clearly visible.

This true-color image shows several fires burning in southern Italy, as well as a couple fires in the northwest of Sicily.

Fires are burning throughout Australia's Northern Territory, seen here in this true-color  image.

This true-color  image shows the detection of dozens of fires burning in Eastern Siberia, Russia.   Heavy smoke shrouds much of the region and stretches out over the East Siberian Sea.

Two images (visible and infrared) are added together to give a final image. The visible band is used to identify the plums of smoke and infrared to spot the hot spot (active fires).

Another two images (visible and infrared) are added to the final image of the wildfire and its scars.

This false-color image over the Bitterroot National Forest, Montana, was made using a combination of the shortwave infrared, near-infrared, and blue wavelengths.

GEOS

This is an image of two fires in the Shenandoah National Park, Virginia. This animation shows smoke from the Shenandoah fire on. The red pixels show the areas that were actively burning. 

This is an oblique image of a fire spread out of control near Los Alamos, New Mexico. You can see the wind factor and its role in spreading fires. 

This is an image of huge wildfires burning in Colorado, Montana, Idaho, Utah, Washington, Nevada, Arizona, New Mexico, Texas, and California. Notice the tremendous area covered by the image.

The above is an image of the forest fires of the Indonesian island of Borneo. It also illustrates a interesting phenomenon. Smoke from fires prevent clouds to from rain. this done by the Precipitation Radar on board of TRMM.

In this image, lightning flashes, overlaid on high-resolution infrared cloud-top data from the orbiting. High flash rates visible indicate the potential for forest fires caused by lightening. This is very common in Siberia, Russia.

This map shows man-made and natural fires for September, 1999. Dark red indicates low numbers of fires (1-5 per month), orange and white represent increasing numbers of fires, up to about 100. The data is derived from the visible and infrared bands.
