Common Core Database (since early 80’s) Existing information on forest fires events collected by the Countries Number of fires Fire location (commune level) Date: start (first alarm) / end Time of intervention / Time of extinction Burnt area: forest / non-forest Cause (unknown, natural, accident, deliberate)
Some Statistics In average around ha burn per year throughout Southern Europe (P, E, F, I, EL). Around 96% of the fires are human caused > 50% of the fires start between 12:00 and 18:00 h > 50% of the burnt area is burned in the same period 50% of the fires have a delay of less than 15 minutes between fire detection and initial attack The average final size of a fire after an initial attack delay of 15 minutes is ~ 8 ha

Fire Detection and monitoring AVHRR ATSR MODIS Most of these fire products show a more or less large overestimation of fire detections (false alarms) in Southern Europe They are only a sample due to reduced number of daily acquisitions
