In reviewing the literature, the earliest report we were able to find describing the observation of fire using a satellite sensor acquiring daily-global earth observations occurred when Croft 1973 described observing fires at night in Africa using photographs generated from the Defense Meteorological Satellite Program DMSP Operational Linescan System OLS visible band data. Croft 1978 was later able to use digital OLS data to observe fires, city lights and gas flares. The first systematic inventory of fires with OLS data was accomplished by Cahoon et al. 1992 who manually digitized fire points from film produced from nighttime OLS orbits over Africa. Since 1972, the U.S. Department of Defense has maintained at least two DMSP platforms carrying OLS sensors in earth orbit. Because of the large data volume and restrictions on access to the data, a digital archive for DMSP-OLS data was not established until 1992. A film archive established in 1974 at the NOAA National Geophysical Data Center holds analog data from approximately 1.7 million OLS orbits acquired in the twenty years prior to 1992.
