GPM+SM2RAIN (2007-2018): quasi-global 25km/daily rainfall product from the integration of GPM and SM2RAIN-based rainfall products

Rainfall dataset based on the integration of IMERG-LR of the Global Precipitation Measurement Mission (GPM) with SM2RAIN-based rainfall estimates derived from ASCAT H113 H-SAF , SMOS L3 and SMAP L3 soil moisture products. The dataset is available +/-60 ° (2007-2018). More details on the grid and data can be found in the netCDF file. The quality flag provided with the dataset has been used to mask out low quality data, as well as the areas characterised by complex topographic, frozen soil, and presence of tropical forests. The associated publication is avalaible on Hydrology and Earth System Science journal

本数据集由全球降水测量任务（Global Precipitation Measurement Mission, GPM）的IMERG-LR产品，与由ASCAT H113 H-SAF、SMOS L3及SMAP L3土壤湿度产品经SM2RAIN算法推导得到的降雨估算结果整合构建而成。该数据集覆盖±60°纬度范围，时间跨度为2007年至2018年。更多关于数据集网格与数据的细节，可在netCDF格式文件中查阅。数据集附带的质量标记已被用于剔除低质量数据，同时掩膜去除了地形复杂、冻土分布以及热带雨林覆盖的区域。相关研究成果已发表于《水文与地球系统科学（Hydrology and Earth System Science）》期刊。
