地球稳定目标微波辐射参考数据集（2015-2019）

微波波段地球稳定目标参考数据集是国产卫星微波辐射计历史数据再定标的辐射参考，用于风云和海洋卫星窗区微波辐射计的辐射校正，主要覆盖了10-89GHz。以美国GPM/GMI为参考载荷，GMI/L1数据为参考数据，通过全球遥感普查筛选出南美亚马逊热带雨林为微波波段满足一定限定条件的地球稳定目标，据此处理生成南美亚马逊热带雨林0.25°×0.25°分辨率分析样区的辐射参考数据集。The Microwave-band Earth Stable Target Reference Dataset is a radiometric reference for the re-calibration of historical data from domestic satellite microwave radiometers. It is used for radiometric correction of window-region microwave radiometers on Fengyun satellites and Haiyang satellites, primarily covering the frequency range of 10–89 GHz. Taking the US GPM/GMI as the reference payload and GMI/L1 data as the reference dataset, the South American Amazon Rainforest was identified as an Earth stable target in the microwave band that meets certain defined conditions through global remote sensing surveys. Based on this, a radiometric reference dataset for the 0.25°×0.25° spatial resolution analysis sample area of the South American Amazon Rainforest was processed and generated.
