摘要
MODIS是美国NASA的ESE计划中最重要的传感器。它具有36个通道,空间分辨率为2 5 0～10 0 0m ,是新一代的图谱合一的遥感仪器。它的数据在地球长期观测、地球环境监测、自然灾害监测方面具有广泛的应用前景和重大意义。本文首先对EOS计划和MODIS仪器的特性进行概述,然后对MODIS的数据产品进行了介绍,再以大气为主,描述了MODIS原始数据到0级数据、1级、2级及更高级产品的处理流程和算法。重点介绍了由0级数据到2级数据的处理过程和IMAPP及其处理结果,并简要的把IMAPP的处理过程与DAAC的进行对比,最后对IMAPP的大气产品进行了详细说明。
MODIS is one of the most important instruments in the ESE of NASA. It is the new generation remote sensing instrument, which has 36 channels with the spatial resolution of 250～100 0m.The data of MODIS could be widely used in the long term observation of the earth, the monitoring of earth environment and natural disasters. In this paper, EOS and the characteristics of MODIS are firstly summarized, then the atmosphere products of MODIS are analyzed. Giving priority to the atmosphere, the procedures and algorithms are described for products which are processed from raw data to level-0, level-1, level-2 and even higher level products. The procedure of data processing from level-0 to level-2 products is presented in detail as well as the result of IMAPP. What is more, the procedures of IMAPP and DAAC are briefly compared. The last section is a detailed description of IMAPP atmosphere products.
