The in-stream water transit time datasets correspond to the recent high-quality global river hydrography dataset named GRADES [Lin. et al. 2019] by sharing "COMID". The shapefiles are publically assessible (link: 'http://hydrology.princeton.edu/data/mpan/GRADES/' and 'http://hydrology.princeton.edu/data/mpan/MERIT_Basins/'). The water transit time datasets cover 8 continents/sub-continents, where the number represents the level 1 Pfafstetter code from HydroSHEDS/HydroBASINS: 1: Africa, 2: Europe, 3: North Asia, 4: South Asia, 5: Oceania and South Asian Islands, 6: South America, 7: North America, 8: Arctic Region. The first colum is COMID inherited from GRADES, the second column is the water transit time in natural status, and the third column is the water transit time in dammed status, all water transit times are in unit of days.
