%X Moderate resolution optical remote sensing data provides opportunities to monitor and discriminate burned area in an accurate way. This study assesses the performance of four different multitemporal compositing techniques using PROBA-V satellite imagery aiming burned area mapping algorithms, namely: first minimum Near Infrared (NIR) reflectance value, second minimum NIR value, combined NIR and ShortWave Infrared (SWIR) values, and maximum Normalize Difference Vegetation Index (NDVI) value. A quantitative assessment of the performance of each compositing technique was achieved by evaluating the ability to discriminate burned and unburned pixels, analyzing clouds/shadows persistence and the frequency of high solar zenith angles view on each compositing. The results showed that the second minimum NIR compositing technique is the most suitable for burned areas mapping, due to its ability to retain burned signals and to eliminate off nadir pixels and those contaminated with clouds/and shadows.
