摘    要:2003年春季国家卫星海洋应用中心等几家单位在黄海和东海海区进行了为期40 d的二类水体信息测量试验,试验中使用手持太阳辐射计对海区上空大气光学特性进行了观测,并获得了大量晴空天气条件下的大气光学数据.利用本次试验获取的测量数据得到了黄海、东海海区春季的大气气溶胶光学特性,其中包括气溶胶光学厚度和气溶胶粒子谱分布.采用Langley方法对测量得到的太阳直射辐射量进行处理得到了海区上空气溶胶光学厚度,利用得到的气溶胶光学厚度来反演气溶胶粒子谱分布.反演结果表明无云情况下黄海、东海上空的气溶胶光学厚度在0.2~0.4左右,且气溶胶粒子谱分布的变化趋势也很接近;海区上空霾层较厚时测量得到的气溶胶光学厚度明显增大,最大接近0.8;气溶胶粒子谱分布的变化趋势发生了明显的变化.

关 键 词:太阳辐射计    气溶胶光学厚度    粒子谱分布    气溶胶光学特性

Abstract:The information of Case Ⅱ water measurement experiment had been made in the areas of the Huanghai Sea and the East China Sea in the spring of 2003.The joint team includes the National Satellite Ocean Application Service and others institutes.In this experiment atmospheric optical characteristics were measured with the hand-held sun-photometers,and obtained a lot of dat a about atmosphere in clear and cloud-free condition.Here these data were used to invert the properties of aerosols over the Huanghai Sea and the East China Sea in the spring days,which include aerosol optical thickness and aerosol size distribution.How to use the Lang ley method to compute the aerosol optical thickness over the sea was described, then the aerosol optical thickness to invert aerosol size distribution was used.The results show that aerosol optical thickness is about 0.2~0.4 over the Huanghai Sea and the East China Sea in the clear and cloud-free days and the trend of aero sol size distribution is very close.In the haze conditions the aerosol optical thickness increases,maximum near to 0.8.At the same time the trend of size distribution changed obviously.
Keywords:sun-photometer  aerosol optical thickness  aerosol size distribution  aerosol optical properties
