+For the monthly files from L4 Ameriflux, we are comparing the
+following quantities with the models:
+
+H_f                       This is sensible heat flux, in units of
+W/m2/day according to Ameriflux documentation
+LE_f                     This is latent heat flux, in units of
+W/m2/day according to Ameriflux documentation
+Rg_f                      This is global radiation, in units of MJ/m2/day
+Reco_or                This is the ecosystem respiration flux, in
+units of gC/m2/day
+NEE_or_fMDS     This is the net ecosystem exchange flux, in units of
+gC/m2/day
+GPP_or_MDS      This is the gross primary production flux, in units
+of gC/m2/day
+
+I do not personally understand the H and LE units for the
+observations and have asked Ameriflux for clarification. Please skip for now.
+
+For Rg_f, please compare with the model variable SOLAR. Please label:
+Shortwave incoming (Wm-2)
+To convert Rg_f to units of Wm-2:
+
+X MJ/m2/day * (1 x 10^6 J/MJ)/(24*3600s/day) = Y Wm-2
+
+For Reco_or please compare with the sum of model variables ar and hr.
+Please label: Re (gC/m2/day)
+For NEE_or_fMDS please compare with model variable nep. Please label
+NEE (gC/m2/day) 
+For GPP_or_MDS please compare with model variable gpp. Please label
+GPP (gC/m2/day) 
+
+The last three model variables have units of KgC/m2/s.  To convert to
+gC/m2/day, please use this approach:
+
+X Kg C/m2/s *(1000 g C/Kg C)*(3600*24 s/day) = Y gC/m2/day
