As a significant source of trace gases and particulate matter to the atmosphere, biomass burning plays an important role in climate change and atmospheric chemistry at regional and global scales. The burned area is a critical parameter in estimating fire emissions. Recently, multiyear global burned area products with medium spatial resolution (1 km or 500 m) have been released, including the L3JRC product and the Collection 5 Moderate-Resolution Imaging Spectroradiometer (MCD45A1) product. In this study, we compare the spatial distribution and temporal pattern of L3JRC and MCD45A1 burned areas over 7 fire years from 1 April 2000 to 31 March 2007. For these 7 fire years, L3JRC gave global burned areas of 3.89, 4.32, 3.53, 4.43, 3.81, 3.60, and 4.51 million km2, and MCD45A1 gave values of 3.44, 3.33, 3.57, 3.38, 3.52, 3.39, and 3.61 million km2, respectively. The L3JRC product showed persistent burning activity from April to October, whereas the burned area according to MCD45A1 often peaked in August and December at the global scale. For most continents, the L3JRC and MCD45A1 burned areas compared very well during the fire season; however, for the period outside the fire season, L3JRC generally reported a significantly larger burned area than did MCD45A1. The burned areas were examined according to the main vegetation classes given by the GlobCover product. Validation of the L3JRC and MCD45A1 burned areas was performed using data from ground-based measurements in Canada, the United States, Russia, and China. The results showed that MCD45A1 was more comparable to reference data, although it often underestimated in the boreal forests. L3JRC generally exhibited significant overestimation in these areas.
