|Abstract:||Abstract This paper reports on the development and validation of a new, global, burnt area product that is unique due to the availability of data in daily time steps. Burnt areas are reported at a resolution of 1km for seven fire years (2000 to 2007). A modified version of a Global Burnt Area (GBA) 2000 algorithm is used to compute global burnt area. The total area burnt each year (2000-2007) is estimated to be between 3.5 million km2 and 4.5 million km2. The total amount of vegetation burnt by cover type according to the Global Land Cover (GLC) 2000 product is reported. A validation strategy involving 72 Landsat TM scenes was undertaken. Correlation statistics between estimated burnt areas are reported for major vegetation types. The accuracy of this new global data set depends on vegetation type. Future work will focus on improving the spatial resolution of the validation strategy.|
