Tropospheric aerosols affect the radiative forcing of Earth's climate, but their variable concentrations complicate an understanding of their global influence. Model-based estimates of aerosol distributions helped reveal spatial patterns indicative of the presence of tropospheric aerosols in the satellite-observed clear-sky solar radiation budget over the world's oceans. The results show that, although geographical signatures due to both natural and anthropogenic aerosols are manifest in the satellite observations, the naturally occurring sea-salt is the leading aerosol contributor to the global-mean clear-sky radiation balance over oceans.
对流层气溶胶影响地球气候的辐射强迫，但其浓度变化使得理解它们的全球影响变得复杂。基于模型的气溶胶分布估计有助于揭示表明对流层气溶胶存在的空间模式，这些模式存在于卫星观测到的全球海洋晴空太阳辐射收支中。结果表明，尽管卫星观测中自然和人为气溶胶产生的地理特征都很明显，但天然海盐是海洋全球平均晴空辐射平衡中气溶胶的主要贡献者。
