Abstract :
Global MODIS Fire products (MOD14) are routinely generated by automated application of the Giglio algorithm (Giglio et al., 2003, Remote Sensing of Environment 87, 273-282) on daytime and night-time data collected up to four time a day. We present here the results and the validation of an Improved Giglio Algorithm for the Detection of Italian Fires (IGADIF). IGADIF presents substantial innovation in the computing of (two) physical parameter estimates at sub-pixel resolution: the top fractional temperature present in candidate Hot-Spot pixels, and the total area involved in the burnout. GIS validation of IGADIF and MOD-14 results are conducted considering two independent set of ground truth data, the record of fire extinguishing operations carried out by the Italian National Firemen Corps (NFC), and the burn scars obtained from ASTER.
