欧空局土壤湿度气候变化倡议(Soil_Moisture_cci)1978-2019年土壤湿度被动遥感产品v05.2

土壤水分CCI被动数据集是欧洲航天局土壤水分基本气候变量(ECV)气候变化倡议(CCI)项目创建的三个数据集之一。该产品是通过合并SMMR、SSM/I、TMI、AMSR-E、WindSat、AMSR2、SMOS和SMAP卫星仪器的数据创建的。还创建了主动和组合产品。
v05.2 PASSIVE产品以NetCDF-4经典文件格式的全球每日图像形式提供，以0.25度的空间分辨率呈现地表土壤湿度的全球覆盖范围。它以体积单位[m3 m-3]提供，涵盖1978-11-01年至2019-12-31年期间(yyyy-mm-dd)。有关产品的理论和算法基础的信息，请参阅算法理论基线文件。其他与数据集相关的参考文件和信息也可以在CCI土壤水分项目网站上找到。

The Soil Moisture CCI Passive Dataset is one of three datasets created by the European Space Agency (ESA) Climate Change Initiative (CCI) project for the Soil Moisture Essential Climate Variable (ECV). This product is developed by merging data from satellite instruments including SMMR, SSM/I, TMI, AMSR-E, WindSat, AMSR2, SMOS, and SMAP. Active and combined products have also been created.

The v05.2 PASSIVE product is provided as global daily imagery in NetCDF-4 Classic file format, offering global coverage of surface soil moisture at a spatial resolution of 0.25 degrees. It is provided in volumetric units [m³ m⁻³] and covers the period from 1978-11-01 to 2019-12-31 (yyyy-mm-dd). For information on the theoretical and algorithmic foundations of this product, please refer to the Algorithm Theoretical Basis Document. Additional reference documents and information related to the dataset are also available on the CCI Soil Moisture Project website.
