The Steinhatchee fire in northern Florida had burned more than 54,000 acres by the end of Thursday, May 24, 2001. The images above show views of the fire from two different satellite sensors. Both instruments viewed the fire at roughly 10:45 a.m. Eastern Daylight Savings Time, May 24, 2001. The top image shows true-color data, with active fires outlined in red. Designed for global climate studies, the satellite circles the Earth from pole to pole, viewing the entire planet every one to two days. The satellite collects data in 36 spectral bands, ranging from blue to thermal infrared. Applications of the data include fire and land surface change monitoring, aerosol and cloud research, and ocean studies.
