Fig.19: Relative fit of WOA01 and WGHC annual mean salinities to the 
observed high-quality data in 200-500 meter layer and below 2000m . 
Values greater than 1 indicate a better fit for the WGHC climatology. 
An important improvement in the WGHC climatology is achieved through a finer vertical 
resolution. Whereas the WOA01 climatology has a relatively large spacing of 500 meters 
between the standard levels below 2000 m, the maximum vertical spacing in our climatology 
is 250 meters. The last level of the WGHC climatology is typically >=100 meters closer to 
the actual (ETOP05) bottom depth compared with the last WOA01 level (Fig. 20). In such
