露天生物质燃烧（OBB）对区域和全球的空气质量、气候变化和人类健康都有重大影响。它容易受到火灾类型的影响，包括森林、灌木林、草地、泥炭地和耕地的燃烧。全球高分辨率卫星在探测活动火灾方面具有优势，可以更准确地估计这些排放。本数据集利用中国风云三号3D卫星的全球火点监测数据、卫星和观测生物量数据、植被指数衍生的时空可变燃烧效率以及基于土地类型的排放因子，建立了全球高分辨率（1km × 1km）的与露天生物质燃烧排放相关的日排放清单。", "ds_source": "

Open biomass burning (OBB) significantly impacts regional and global air quality, climate change, and human health. It is susceptible to fire types, including forests, shrublands, grasslands, peatlands, and croplands burning. Global high-resolution satellites have advantages in detecting active fires, enabling more accurate estimation of these emissions. In this study, we develop a global high-resolution (1 km×1 km) daily emission inventory associated with OBB emissions using the Chinese Fengyun-3D satellite’s global fire spot monitoring data, satellite and observational biomass data, vegetation index-derived spatiotemporal variable combustion efficiency, and land type-based emission factors.
