World Ocean Circulation Experiment - Argo Global Hydrographic Climatology
The paper describes the new gridded World Ocean Circulation Experiment-Argo Global Hydrographic Climatology (WAGHC). The climatology has a 1/4 degrees spatial resolution resolving the annual cycle of temperature and salinity on a monthly basis. Two versions of the climatology were produced and diffe...

The paper describes the new gridded World Ocean Circulation Experiment-Argo Global Hydrographic Climatology (WAGHC). The climatology has a 1/4 degrees spatial resolution resolving the annual cycle of temperature and salinity on a monthly basis.
