I use Noah-MP land surface scheme to run WRF4.4 over Europe.

Energy budget is usually expressed as Rnet = SH + LH + G, in which Rnet means net radiation flux, SH means sensible heat flux, LH means latent heat flux, and G means ground heat flux.

The following pictures show the averages of the year 2019. We can see that the remaining energy item (i.e., the first picture in the left) is relatively large.

I check the module_sf_noahmplsm.F, and find the energy budget expressed as the follows,

ERRENG = SAV+SAG-(FIRA+FSH+FCEV+FGEV+FCTR+SSOIL+

**FIRR**+

**CANHS**) +

**PAH**

ERRENG should < 0.01

I think the equation may correspond to ERRENG = SAV+SAG -FIRA -(SHC+SHB+SHG)-(EVC+EVB+EVG)- (GHV+GHB). But I have no idea about the final three variables.

I wonder whether the three variables (i.e., FIRR, CANHS, PAH) are outputed by the model and what their name exactly are in the wrfout files. I have tried to find the above variables, but the potential variables such as ACCANHS,ACPAHB,ACPAHG,ACPAHV,IRRSPLH,IRELOSS all have values of zero.

I have spent many days to understand it, but unluckily I still could not. I sincerely hope someone could help me. Many thanks!
