Relationship between dust aerosol and solar radiation in gebi desert in North China was analyzed based on observational and calculative data, such as TOMS aerosol index (AI), total astronomical radiation, total solar radiation and dust visibility. in China mainland. It turns out that there were perfect correlation and same trend between the total solar radiation and AI, suggesting that the thermal convection triggered by solar radiation was the most important factor for dust aerosol. It also shows that the input of dust aerosol in atmosphere would affect solar radiation significantly and persistently. Besides these, the ratio of absorption and scattering of solar radiation by dust aerosol between fine days and sandstorm was above 60%.

Based on the analysis of the TOMS-AI (Aerosol Index) and extraterrestrial radiation, the relationships between the dust aerosol loading and solar radiation in global dust source regions are examined. There are high correlations between solar radiation and the TOMS-AI in the dust source regions of both Northern and Southern Hemisphere. It is found that solar radiation is one of the most important factors influencing the dust aerosols in the desert regions.
