WOCE-Argo Global Hydrographic Climatology (WAGHC Version 1.0)
Project: WOCE-Argo Global Hydrographic Climatology - The WAGHC is a full-depth one-fourth degree resolution temperature and salinity climatology describing the mean state of the World Ocean between 1996 and 2011, with monthly gridded fields available between the surface and 1778 m depth.
