Article Synopsis
  • Biomass burning (BB) emits aerosols that significantly influence climate factors like radiation balance and cloudiness in tropical areas, but there's a lot of uncertainty in assessments due to reliance on global models.
  • By using observations from both satellite and ground sources, researchers constrained the aerosol absorption optical depth (AAOD) specifically in the Amazon and Africa, identifying major error sources for each region.
  • The study found that correcting these errors can reduce differences in aerosol radiative effects among models by threefold, suggesting a stronger potential for improving the understanding of radiative forcing from biomass burning aerosols.

Biomass burning (BB) is a major source of aerosols that remain the most uncertain components of the global radiative forcing. Current global models have great difficulty matching observed aerosol optical depth (AOD) over BB regions. A common solution to address modelled AOD biases is scaling BB emissions.

Even though desert dust is the most abundant aerosol by mass in Earth's atmosphere, atmospheric models struggle to accurately represent its spatial and temporal distribution. These model errors are partially caused by fundamental difficulties in simulating dust emission in coarse-resolution models and in accurately representing dust microphysical properties. Here we mitigate these problems by developing a new methodology that yields an improved representation of the global dust cycle.
