矿物沙尘气溶胶通过与云、生态系统和辐射的相互作用影响地球的辐射收支，这在理解过去和预测未来气候变化方面构成了很大的不确定性。这种巨大不确定性的原因之一是对排放的沙尘气溶胶的粒径分布了解甚少。本研究表明，区域和全球环流模式（GCMs）高估了黏土气溶胶的排放比例（
Mineral dust aerosols impact Earth's radiation budget through interactions with clouds, ecosystems, and radiation, which constitutes a substantial uncertainty in understanding past and predicting future climate changes. One of the causes of this large uncertainty is that the size distribution of emitted dust aerosols is poorly understood. The present study shows that regional and global circulation models (GCMs) overestimate the emitted fraction of clay aerosols (
