how to calculate net surface heat flux

[hui_ding@colorado_edu]

I found the following four atmospheric variables: FLNS (net longwave at the surface), FSNS (net shortwave at the surface), LHFLX (latent heat flux) and SHFLX (sensible heat flux). But I have no idea whether positive values means flux into the ocean or atmosphere. How should I calculate net surface heat flux into the ocean using the four variables?
Thank you!

Hi,

Does this answer help?

Sign definition about SHFLX/LHFLX

Hello！ I am new to using the cesm model. I have been confusing the signs of sensible heat flux and latent heat flux output by the cesm. Are the positive values transferred from the ocean to the atmosphere or from the atmosphere to the ocean? And what about the symbol for net solar radiation...
