摘要:

200710月份中国海洋大学的东方红2号科考船在北黄海海区进行了为期12天的秋季908航次的数据测量实验,试验中使用了日本PREDE公司生产的POM01-MKII 7波段全自动天空辐射计对该海区上空的大气进行了观测,获取了大量的气溶胶光学数据。对光学数据处理后得到了气溶胶光学厚度(AOT)、单次散射反照率(SSA)、气溶胶粒径体积谱分布。结果表明:在无云晴天的情况下,500 nm处的AOT最大值在0.36以下,870 nmAOT值在0.15以下,有雾或阴霾情况下AOT 值偏大,是无云情况下的5倍左右;从单次散射反照率来看,该海区上空在秋季气溶胶有吸收的情况,离岸近,吸收较强,离岸远,吸收较弱;从粒径体积谱分布来看,陆源聚类粒子含量的高低与气溶胶的吸收有很大的关系。

Abstract:

Dong Fang Hong No.2, a scientific survey ship belonging to Ocean University of China ,has a voyage on the North Yellow Sea in China during the period from 14th to 25th in October of 2007 . The aim for this sailing is to attain aerosol optical properties data in that sea area. During the voyage, POM01-MKII, a seven bands auto sky radiometer made in Japan, was used in order to measure the preciseaerosol optical data and it got lots of true measurement data. After dealing with the data, aerosol optical thickness(AOT), single scattering albedo(SSA), and columnar volume spectrum were obtained. The results showed that the value of AOT at 500 nm is less than 0.36 and the value at 870 nm is less than 0.15 when it has no cloud. Under the situation of fog or haze, the value of AOT is approximate 5 times bigger than that of without cloud;seeingfrom SSA, aerosol lies in absorption over the North Yellow Sea and the rule is that the nearer the distance to the bank is, the stronger the absorption is; the further the distance to the bank is, the weaker the absorption is; seeing from columnar volume spectrum, accumulation particle content from land has a largely relation with the absorption of aerosol.

Key words: sky radiometer, aerosol optical thickness, single scattering albedo, aerosol columnar volume spectrum
