Daily 0.05⁰×0.05⁰ land surface soil moisture dataset of Qilian Mountain area (SMHiRes, V1)

This dataset contains daily 0.05⁰×0.05⁰ land surface soil moisture products in Qilian Mountain Area in 2017. The dataset was produced by utilizing the multivariate statistical regression model to downscale the “AMSR-E and AMSR2 TB-based SMAP Time-Expanded Daily 0.25⁰×0.25⁰ Land Surface Soil Moisture Dataset in Qilian Mountain Area (SMsmapTE, V1)”. The auxiliary datasets participating in the multivariate statistical regression include GLASS Albedo/LAI/FVC, 1km all-weather surface temperature data in western China by Ji Zhou and Lat/Lon information.

本数据集包含2017年祁连山地区每日0.05⁰×0.05⁰的地表土壤湿度产品。该数据集通过多元统计回归模型，对“基于AMSR-E和AMSR2亮温（TB）的祁连山地区SMAP时间扩展每日0.25⁰×0.25⁰地表土壤湿度数据集（SMsmapTE，V1）”进行降尺度处理生成。参与多元统计回归的辅助数据集包括GLASS反照率（Albedo）/叶面积指数（LAI）/植被覆盖度（FVC）、周佶（Ji Zhou）团队的中国西部1km全天候地表温度数据，以及经纬度（Lat/Lon）信息。
