Daily Global Land Parameters Derived from AMSR-E and AMSR2, Version 2

This data set contains satellite-retrieved geophysical parameter files generated from the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the National Aeronautics and Space Administration (NASA) Aqua satellite and the Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on the JAXA GCOM-W1 satellite. The geophysical parameters include daily air surface temperature, fractional open water cover estimates, vegetation optical depth, surface volumetric soil moisture, and atmosphere total column precipitable water vapor. The global retrievals were derived over land for non-precipitating, non-snow, and non-ice covered conditions.

本数据集包含由搭载于美国国家航空航天局（National Aeronautics and Space Administration, NASA）Aqua卫星上的高级微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer - Earth Observing System, AMSR-E）仪器，以及搭载于日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency, JAXA）GCOM-W1卫星上的高级微波扫描辐射计2（AMSR2）传感器生成的卫星反演地球物理参数文件。该数据集涵盖的地球物理参数包括每日地表气温、开放式水域覆盖占比估算值、植被光学厚度、表层体积土壤湿度以及大气总柱可降水量。本次全球反演产品基于陆地表面，仅适用于无降水、无积雪且无冰覆盖的场景。
