title: Estimates of black carbon emissions from global biomass burning for the period 1997–2023

description: Estimating black carbon (BC) emissions from biomass burning is
 crucial for accurately assessing the climate impact of this pollutant. In
 this study, We have estimated BC emissions from biomass burning in
 different geographic regions worldwide at a resolution of 0.25°×0.25° from
 1997 to 2023. These findings are crucial for accurately modeling the
 impact of BC on global climatic forcing. Over the past 27 years, the
 emissions of BC from global biomass burning activities have remained
 stable. The high BC emissions between 2003 and 2008 were associated with
 increased precipitation. The SHSA and SHAF regions have emerged as the
 primary contributors, accounting for approximately 40% of total BC
 emissions originating from global biomass burning sources and
 high BC emissions in the southern hemisphere's spring. This study
 also reveals that BC emissions in the SHAF region during
 1997–2023 exhibit a Granger causal relationship with Antarctic sea ice
 loss at a two-year lag, but the impact intensity demonstrates significant
 temporal heterogeneity. This study enhances our understanding of
 temporal and spatial variations in global BC release caused by biomass
 burning while providing fundamental data for international departments
 responsible for managing such activities.
