海洋大气气溶胶光学模型参数的相关性研究

Study on the Relation of Ocean Atmospheric Aerosol Optical Model Parameters

气溶胶光学模型参数在气溶胶遥感和气候强迫研究中都具有重要的作用。通过对全球近90个气溶胶自动观测网(AERONET)的海洋站点数据进行筛选、分类和分析,发现了气溶胶模型的中值半径及其标准偏差间的负相关性,并给出了经验关系。利用该关系对现行中分辩率成像光谱仪(MODIS)海洋气溶胶模型进行了评估,并指出了该模型存在的不足。

Aerosol optical model parameters are important for aerosol remote sensing and climate forcing study. The negative correlation between the standard deviation and number median radius has beam established based on the ocean Aerosol Robotic Network （AERONET） data worldwide empirical relation is proposed. Moderate-resolution imaging spectroradiometer （MODIS） ocean aerosol models are assessed by using this relation, and some shortcomings have been discussed.
