黄海海域气溶胶光学厚度测量研究
Ground Surface Observation of Aerosol Optical Thickness Over Yellow Sea Region
摘要
了解海洋上空大气气溶胶的变化情况具有重要的科研和应用价值.本文在讨论了太阳辐射计的标定、大气气溶胶光学厚度的计算和Angstrom参数的计算等问题的基础上,介绍了利用多波段太阳辐射计对黄海海域气溶胶光学厚度的测量和研究.测量结果表明黄海海域大气气溶胶主要由自然来源的气溶胶构成,气溶胶光学厚度在0.1左右,光学厚度的日变化和逐日变化不大,Angstrom波长指数约为1.2,大气混浊度指数在0.05左右.
Abstract
Ground-based measurements of the aerosol optical thickness at an island are taken from October 17, 2000 to November 2, 2000 to achieve information of ocean aerosol properties with a multibands sunphotometer. In this paper, the calibration of sun photometer, the calculation of atmospheric aerosol optical thickness and the Angstrom parameters a and β obtained from aerosol optical thickness are discussed. The results show that in Yellow Sea the atmospheric aerosol consists of nature aerosol and aerosol optical thickness is approximately 0.1 in the most cases. Generally, Angstrom parameter a is nearly 1.2 and β is nearly 0.05.
