Description of the Antarctic Resources Center and links to its workshops and archives of Antarctic maps, charts, satellite images, and photographs produced by the member nations of the Scientific Committee on Antarctic Research (SCAR).
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
