abstract = "Knowledge about the current fire dynamics in the Brazilian
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.",
