23 October 2007. SOUTHERN CALIFORNIA WILDFIRES BURN OUT OF CONTROL: NEW NASA SATELLITE IMAGES SHOW FIRES' RAPID GROWTH. By Laura Spector, NASA Goddard Space Flight Center. Excerpt: NASA satellites continue to capture remarkable new images of the wildfires raging in Southern California. At least 14 massive fires are reported to have scorched about 425 square miles from north of Los Angeles to southeast of San Diego.
The latest images, captured by NASA satellites on the afternoon of October 22, show the thick, billowing smoke coming off the numerous large fires and spreading over the Pacific Ocean.
Dry, drought-stricken vegetation and Santa Ana winds, which can reach hurricane speeds, have contributed to the devastating effect of these blazes.... According to news reports, almost 700 homes have been destroyed and hundreds of thousands of residents have been forced to evacuate.
...A pair of images, depicting the area around Los Angeles on October 21, 2007, shows just how quickly the fires grew. According to the National Interagency Fire Center, the blazes have burned over 84,000 acres since they began over the weekend. Thousands of residents have been evacuated from their homes and a state of emergency has been issued for 7 California counties.

July 15, 2002, Urbanization's Aftermath -- Using satellite images of city lights at night, [a group of researchers at NASA's Goddard Space Flight Center led by biologist and remote sensing specialist Marc Imhoff] constructed a map of the urbanized areas of the United States. They then retrieved vegetation density readings of present day American cities as well as simulated readings of the landscapes that pre-dated these cities. By combining the vegetation data with the urbanization maps, Imhoff was able to calculate the effects of urbanization on many types of ecosystems across the country.
