AMSR-E/Aqua Daily Global Quarter-Degree Gridded Brightness Temperatures, Version 1

The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA EOS Aqua satellite provides global passive microwave measurements of the Earth. NSIDC produces AMSR-E gridded brightness temperature data by interpolating AMSR-E data (6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz) to the output grids from swath space using an inverse-distance squared method. AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures (AE_L2A) input source data are used to create the gridded brightness temperature data.搭载于美国国家航空航天局（NASA）地球观测系统（Earth Observing System, EOS）Aqua卫星上的先进微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer - Earth Observing System, AMSR-E）载荷，可获取全球范围的地球被动微波观测数据。美国国家雪冰数据中心（National Snow and Ice Data Center, NSIDC）采用反距离平方插值法，将AMSR-E的条带观测数据（涵盖6.9 GHz、10.7 GHz、18.7 GHz、23.8 GHz、36.5 GHz与89.0 GHz六个频段）从条带空间插值至规则输出网格，以此生成AMSR-E网格化亮温数据。本次网格化亮温数据的生成，以AMSR-E/Aqua L2A全球条带空间重采样亮温数据（AE_L2A）作为输入源数据。
