Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 2

The Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 2 data set is a multi-sensor Level 3 Earth Science Data Record (ESDR) with improvements upon Version 1 in cross-sensor calibration and quality checking, modern file formats, better quality control, improved projection grids, and local time-of-day (LTOD) processing. These data are gridded to three EASE-Grid 2.0 projections (North Azimuthal, South Azimuthal, and Cylindrical) and include enhanced-resolution imagery, as well as coarse-resolution, averaged imagery. Inputs include brightness temperature data from the Scanning Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave/Imager (SSM/I), Special Sensor Microwave Imager/Sounder (SSMIS), Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E), and Advanced Microwave Scanning Radiometer 2 (AMSR2).校准增强分辨率被动微波逐日EASE-Grid 2.0亮温地球科学数据记录（Earth Science Data Record, ESDR）第二版数据集，属于多传感器三级地球科学数据记录产品。相较于第一版，该数据集在跨传感器校准与质量核查、现代化文件格式、更完善的质量管控、优化的投影网格以及本地当日时间（local time-of-day, LTOD）处理等方面均实现了显著改进。该数据被网格化至三种EASE-Grid 2.0投影模式（北方位投影、南方位投影与圆柱投影），同时包含增强分辨率影像与粗分辨率平均影像。其输入数据源涵盖扫描多通道微波辐射计（Scanning Multichannel Microwave Radiometer, SMMR）、专用传感器微波成像仪（Special Sensor Microwave/Imager, SSM/I）、专用传感器微波成像仪/测深仪（Special Sensor Microwave Imager/Sounder, SSMIS）、先进微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer - Earth Observing System, AMSR-E）以及先进微波扫描辐射计2号（Advanced Microwave Scanning Radiometer 2, AMSR2）所获取的亮温数据。
