摘要
MODIS数据作为中国可见光遥感的重要数据源之一,目前已经在许多领域获得了重要应用。国家卫星海洋应用中心从2000年开始接收处理MODIS数据,并同时为海冰预报提供海冰遥感图像服务。本文利用MODIS卫星遥感的原始数据,通过对数据进行地理定位、辐射定标等处理,形成MODIS数据的一级产品,并利用海冰实验的实测数据和海冰光谱分析,对一级产品进行定量化处理,获得了海冰厚度、密集度和外缘线等海冰数值产品,逐步应用于海冰的预报服务。
As an important data resource of remote sensing of visual light in China, MODIS data it has been applied in many fields. It has been received and processed since 2000 in National Satellite Ocean Application Service. Been processed of the geolocation and radiometry calibration, MODIS data is used in this article to get the first level products. Through the data of sea ice experiment and the spectral analysis of sea ice, the first level products are processed to get the ice thickness and the digital ice thickness and ice boundary products. All of these are to be applied in the forecasting of sea ice.
