## 4 Results  
The AQM-PROBA algorithm performance was assessed through a comparison with the MCD64A1 product and the Landsat fire reference perimeters. For the whole study area, 12,848 km\({}^{2}\) of the burned area were mapped using the AQM-PROBA algorithm, and 10,332 km\({}^{2}\) for MCD64A1, against 13,086 km\({}^{2}\) mapped in the reference map. In general, the overall accuracy for AQM-PROBA and MCD64A1 were high (Table 4), which is expected since the target class is much less frequent than the non-occurrence class. Figure 4 shows boxplots for the accuracy measures of all the L8 scenes, for both BA products. AQM-PROBA yielded higher bias values than MCD64A1 (Figure 4c), whereas both products showed similar results for DICE and CSI (Figure 4d,e). AQM-PROBA showed lower mean values of OE (30%) and higher CE (22%) than the MCD64A1 (34% and 15% of OE and CE, respectively). The verification measures for both products were also assessed individually for each Landsat scene (Table 4). The highest OE and CE values were recorded for the 221/071 scene, while BIAS values ranged from 0.40 (for MCD64A1 in the scene 221/071) to 1.18 (AQM-PROBA for 219/068). The DICE and CSI coefficients have similar values, with highest values for scenes 219/072, 220/68 and 222/67 (AQM-PROBA) and 219/068, 219/070, 220/067 (AQM-PROBA and MCD64A1). \begin{table}
