clm5.0 single-point simulation near-surface sensible heat flux and latent heat flux are inverse to the observed values

Dear all
When I use clm5.0 to perform a single-point simulation, I found that the near-surface sensible heat flux and latent heat flux are opposite to the observed values, and the sensible heat flux is negative as a whole, and the latent heat flux is nearly half smaller than the observed value. Is there any scholar who can give me some suggestions? Many thanks!

You could look at your atmospheric forcing in the history output to see if it is what you expect (TBOT, QBOT, FSDS, FLDS, WIND, PBOT, ZBOT).

Thank you for your reply. I have repeatedly checked the atmospheric forcing data,it is no problem. I also selected a typical sunny day to test the results of the model simulation, but it is still very bad. Is this because the model defaults to the Is there a problem with the underlying feature? thank you for your reply!

I can't really guess at what's wrong unless I can see some plots. Perhaps diurnal cycle plots of net radiation, latent, sensible, and ground heat flux, compared to the observations, for the sunny day.
Where is this site and what are the surface characteristics?
