相对湿度对大气气溶胶可见辐射吸收的影响

INFLUENCE OF RELATIVE HUMIDITY ON ABSORPTION OF VISIBLE RADIATION OF AEROSOL

本文实验测量了在不同相对湿度下大气气溶胶吸收系数，研究了气 溶胶可见辐射吸收性能和单一排放源排放的气溶在不同相对湿度下的吸收性质及 吸收系数大小．实验结果表明，相对湿度对大气气溶胶可见辐射吸收有较大的影 响，大气气溶胶吸收系数随相对湿度增加而增大，而相对湿度对单一排放源的气溶 胶几乎无影响，这与近期国内外同类研究结果相一致。

Absorption coefficients of aerosol are measured by experiments with different relative humidities. The visible radiation absorption coefficients of aerosol of single source have been studied. Results show that relative humidity has obvious effects on visible radiation absorption of aerosol and no influence on the aerosol of single source.
