| FIRE TOWERS IN THE SKY: NEW MAPS SHOW GLOBAL FIRE PORTRAIT OVER THE COURSE OF A YEAR | G02-068 | 8/29/02 | 00:16:48 | New satellite maps showing fire activity across the entire Earth for the past year are providing a unique picture of seasonal and yearly fire activity. The maps are a milestone in the use of satellite data for creating a long-term fire record that is crucial for understanding the impact of fire on life and climate. This video collection contains highlights from the new global maps and some of the most dramatic satellite pictures from the active 2002 U.S. fire season.

TAPE CONTENTS: |
| ITEM (1): Fiery Planet - Global Portrait of Fire -These Terra maps demonstrate fire behavior that would surprise most people. High-profile fires that occur in the western United States each year tend to draw a lot of attention, but nearly the entire African continent south of the Sahara Desert appears to burn each year. As far as total acreage and number of fires, the widespread fires that burn each year in Africa, Asia, and Brazil dwarf even the most significant fire season in the western United States. Terra's sensors picked up about one million fires during August 21, 2001 to August 20, 2002. In these images, each fire detected is represented by yellow to red colors.

| ITEM (3): Smoke and Fire From 2002 US Fire Season - Images from Terra have become a regular part of the National Interagency Fire Center's firefighting toolkit. The images help the center track fires on a daily basis and are used in allocating precious firefighting resources. The data for these images was collected by Terra's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. MODIS has the ability to see through the smoke to locate active fire areas (seen in red).
a. Colorado Haymen Fire; June 8, 2002
b. Rodeo Chediski, Arizona; June 19, 20, 21, 22, 23, 24, 26 and 30
c. California McNalley Fire; July 22, 2002
d. Oregon Biscuit and Tiller Fires; July 31, 2002

| ITEM (4): Rodeo-Chedeski and Fire Recovery Efforts -Forest officials use satellite images to access active fire regions and to analyze the fire's burn scar. This information helps them quickly plan recovery strategies aimed at protected watersheds and at reseeding denuded patches of forest. On June 21, 2002, the Rodeo and Chediski Fires in east-central Arizona were still two separate fires. This true-color scene from the Enhanced Thematic Mapper Plus instrument onboard the Landsat 7 satellite shows the massive quantities of smoke streaming northward from the fires, which were burning about 100 miles east-northeast of Phoenix. The smaller Chediski Fire is on the right, and the Rodeo Fire is on the left. Over the weekend of June 22, the two fires merged into a single 300,000+ acre blaze. The second image penetrates the smoke to show the active flame area. The third image shows the burned areas that help forest experts plan and execute forest recovery.

| ITEM (5): Tracking Smoke and Pollution From Fire - Fires can create dense blankets of pollution which impact human health. The Terra satellite carries an instrument allowing scientists to track the carbon monoxide generated by worldwide fires and other human activities. These images show how high concentrations of carbon monoxide, shown in red, travel across continental boundaries. The observations represent a powerful new tool for identifying and quantifying pollution sources associated with fire and for observing the transport of pollution on international and global scales. The data for these images were collected by the MOPITT instrument (Measurements of Pollution in the Troposphere) on board the Terra Satellite.

| ITEM (6): Smoke and Smog From Fires -These satellite images show extreme haze and smog associated with wildfires. Scientists say black carbon associated with these clouds can change regional climates by blocking sunlight and warming the upper atmosphere. These images were captured by NASA's Sea Viewing Wide Field of Sensor (SeaWiFS) instrument onboard the OrbView-2 satellite.
