"The Algerian forest fires dataset consist of data on forest fires occurrence in Algeria related to meteorological observations and the fire weather indices. Our dataset includes mainly the daily meteorological observations and the Fire Weather Index (FWI) system components. Given the limited temporal and spatial scope of the initial Algerian forest fires dataset that includes 244 instances, we have constructed a new extended dataset that includes 1215 instances, with 971 new instances and the 244 instances of the initial dataset."
