New publication in "Science of Remote Sensing" by Ouattara et al.

We have a new publication in "Science of Remote Sensing" by Ouattara et al. dealing with the detection of burned areas in Sub-Saharan Africa. Since 2001, the MODIS sensor has been a key tool for tracking global burned areas (BA), but as its mission comes to an end, the VIIRS sensor is stepping in to ensure this critical data continues. A newly developed hybrid algorithm, using VIIRS reflectance and active fire products via Google Earth Engine, was tested in sub-Saharan Africa for 2019. The results are promising, identifying 5.1 million km² of burned areas, with accuracy improving over existing global products. While VIIRS-BA excels at detecting fires that other systems miss, some overestimation occurs in areas with intense fire activity. Future upgrades aim to fine-tune accuracy and reduce errors, ensuring even more reliable fire detection. For more details you can access the study under https://doi.org/10.1016/j.srs.2024.100165.
