NOTES
1.  Comparison Error, E=D-S, where D is the data value, and S is the simulation value.  E% is obtained by normalizing by benchmark, i.e., E%=(D-S)/(validation scale)*100

2.  UV = sqrt(UD2+USN2) is the validation uncertainty [see equation 33 of  Stern et al. (1999)]

3.  UD is the data uncertainty.

4.  USN is the simulation numerical uncertainty [see equation 8 of Stern et al. (1999)]
