HydroATLAS by WWF
BasinATLAS is a component of the HydroATLAS database, which is a component of HydroSHEDS. BasinATLAS provides a standardized compendium of hydro-environmental attribute information for all watersheds of the world at high spatial resolution. This dataset includes data for 56 variables, partitioned into 281 attributes and organized in six categories: hydrology; physiography; climate; land cover & use; soils & geology; and anthropogenic influences (see Table 1 in the HydroATLAS documentation linked below). Watersheds range from level 1 (coarse) to level 12 (detailed), using Pfastetter codes. The underlying watershed deleniation uses the NASA SRTM Digital Elevatin Map (DEM) below 60oN latitude and the USGS HYDRO1k DEM above 60oN. Technical documentation:

GRACE BY NASA
Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 30+ year quasi-global rainfall dataset. CHIRPS incorporates 0.05° resolution satellite imagery with in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.
