FY-3D Global Active Fire product

Wild fires have a strong negative effect on environment, ecology and public health. However, the potential degradation of mainstream global fire products leads to large uncertainty on the effective monitoring of wild fires and its influence. To fill this gap, we produced FY-3D global fire products with a similar spatial and temporal resolution, aiming to serve as the alternative and continuity for MODIS global fire products. For visual-check-based accuracy assessment, five typical regions, Africa, South America, Indo-China Peninsula，Siberia and Australia, across the globe were selected and the overall accuracy exceeded 94%. Meanwhile, the consistence between FY-3D and MODIS fire products was examined. The result suggested that the overall consistence was 84.4%, with a fluctuation across seasons, surface types and regions. Based on field-collected reference data, we further evaluated the suitability of FY-3D fire products in China. The overall accuracy and accuracy (without considering omission errors) was 79.43% and 88.50% respectively. This dataset inlcude global fire products from 2018 to 2022.
