Soil moisture product merged from satellite and modelled data for Great Britain, April 2015-December 2017

A soil moisture product for Great Britain at two spatial resolutions: 12.5km and 1km, based on triple collocation error estimation and a least-squares merging scheme. Two remote sensing soil moisture datasets (one passive microwave dataset: SMAP, and one active microwave dataset: ASCAT) and a modelled soil moisture dataset (from JULES-CHESS land surface model) were combined to produce this dataset. The dataset covers the period going from 1st April 2015 to 31st December 2017, at a daily timestep, and is available at two spatial resolutions: 12.5km; and 1km, which has been obtained after resampling all three underlying datasets to a 1km resolution.

本数据集为英国土壤湿度产品，采用两种空间分辨率：12.5公里和1公里，基于三重交叉误差估计与最小二乘合并方案构建。该数据集融合了两个遥感土壤湿度数据集（一个被动微波数据集：SMAP，以及一个主动微波数据集：ASCAT）和一个模型化土壤湿度数据集（源自JULES-CHESS地表模型），旨在提供全面覆盖。数据覆盖范围自2015年4月1日至2017年12月31日，每日更新一次，并在两种空间分辨率下提供：12.5公里；以及1公里，此分辨率通过将所有三个基础数据集重采样至1公里分辨率而获得。关于本数据集的详细信息，请参阅：https://doi.org/10.5285/26b8ddd4-09fd-4e40-a556-6a8f3a7481ea
