Abstract: Our objective is to monitor vegetation recovery after the large fires of 2003 in Portugal. We use a time-series of MODIS Terra Enhanced Vegetation Index (EVI) data, at 250 m spatial resolution and with 16-day image composites (MOD13A1 product). These data were screened with the Time Series Generator (TiSeG) software, to detect and replace bad or missing data. The analysis begins in early 2000, to characterize pre-fire vegetation dynamics, extends until late 2008, and relies on fire perimeters mapped from Landsat imagery at 30m spatial resolution to locate the 2003 fires. Three sample fires were selected for preliminary visual analysis of EVI time series within and outside the fire perimeters, and observed differences are discussed as a function of pre-fire land cover.
