全球主要沙源区沙尘气溶胶与太阳辐射的关系

Relationship between dust aerosols and solar radiation in global dust source regions

利用TOMS AI气溶胶指数和天文辐射资料对全球主要沙漠区沙尘气溶胶含量与太阳辐射的关系进行验证.结果表明,无论是北半球的沙漠还是南半球的沙漠,其沙尘气溶胶指数和太阳辐射都有非常高的相关性.事实和理论均表明太阳辐射是影响沙漠地区沙尘气溶胶含量主要的因子之一.

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.
