High Mountain Asia daily discharge data

This dataset supports the study Accelerating River Discharge in High Mountain Asia (AGU Advances). It provides daily river discharge for more than 110,000 river reaches across High Mountain Asia.

MERIT_hma.shp Description: Shapefile for geolocating river reaches Note: The COMID field in the shapefile matches the reach values in HMADD.nc allowing spatial linkage between discharge time series and river segments based on MERIT-Basin products (Yamazaki et al, 2019; Lin et al., 2019).
