Two new algorithms have been developed and tested for the ATSR World Fire Atlas, one based on basic thresholding on the 1.6 Micron channel in order to fully exploit the ATSR-1 time series back to 1991 called Algo 3 and a second one based on geographic and time adaptive thresholding called Algo 4. The two algorithms have been prototyped and tested under different conditions, and their results are discussed in respect to Algo 1 and Algo 2 implemented since 15 years. Pros and cons of using the results of Algo 3 and Algo 4 instead of (or in synergy with) Algo 1 and Algo 2 are discussed depending on the land cover and season.
