                         Savannas (Cerrado) relies heavily on satellite-derived burned area 
                         (BA) products applied at the biome level. Nevertheless, there is 
                         still a lack of studies analyzing the consistency of available 
                         available satellite products concerning BA location and extension 
                         for the region. Accordingly, we performed an accuracy assessment 
                         of the MODerate resolution Imaging Spectroradiometer (MODIS) 
                         collection 6 BA product (MCD64 /C6) over 222,768,000 ha 
                         encompassing the Brazilian Cerrado. We used reference data derived 
                         from Landsat-8 OLI to perform an intercomparison of MCD64/C6 with 
                         1) the previous collection 5.1 (C5.1); 2) independent active fires 
                         from the Visible Infrared Imaging Radiometer Suite (VIIRS); and 3) 
                         recent land use patterns. The results of the comparison between C6 
                         and C5.1 indicate that the new collection decreases the omission 
                         error in 90% of the analyzed area and increases the burn hits, 
                         providing improved BA estimates in 61% of the region. However, the 
                         MCD64 product increases the overall commission errors in 74% of 
                         the area. The MCD64/C6 product showed a high coefficient of 
                         correlation with active fires independently detected by VIIRS 
                         (\τ = 0.74). For both MCD64 collections 5.1 and 6, the 
                         different accuracy assessment measures exhibited a marked 
                         performance deterioration from the north towards the south. The 
                         largest burn scars and total affected areas occur mainly across 
                         the northern Cerrado, explaining the better performance in that 
                         area. Conversely, greater inaccuracies were found in the southern 
                         Cerrado area, where natural vegetation has been converted into 
                         pasture and cropland, leading to fragmented landscapes and small 
                         fire patches. Finally, the BAs mapped by both collections were 
                         similar in location albeit divergent in the magnitude, with C6 
                         detecting 21% more area than C5.1 during the year 2015.",
