Global continental discharge estimates from ocean mass balance

These files include a time series of global continental discharge estimated from ocean mass balance following Chandanpurkar et al., 2017. 

The ocean mass balance is obtained from these components:

dM/dt (change in ocean mass): From altimetry and from GRACE/FO. When derived from altimetry, steric level change is subtracted from the GMSL using EN4.2.2 temperature and salinity data. 

E-P: Here, two methods are used:

1. Directly, using estimates of ocean E and P, using OAFlux for E and GPCP and CMAP separately for P

2. Indirectly, using atmospheric moisture balance using vertically integrated horizontal moisture flux divergence, and change in the total column water vapor. These are obtained using ERA5 and MERRA-2 reanalyses products.

The eight discharge estimates are combinations of the above, and the exact combination is mentioned in the filename.
