We are trying to couple our land surface model into WRF. As a first step, we'd like to know what is the minimal list of variables required by such coupling?

$\begingroup$ This depends on your land surface model. Create a list of all the inputs, and find their appropriate variables in WRF. Then create a list of all the outputs, and update the WRF variables that you want. The latter is completely up to you. $\endgroup$– milancurcicCommented Apr 20, 2018 at 13:17

$\begingroup$ But what's the minimal requirement to make the coupling work? I see existing LSMs in WRF all have different input/output lists. Can I take the slab model, which has the minimal list of input/output variables, as the minimal case? $\endgroup$– sunt05Commented Apr 20, 2018 at 13:24

$\begingroup$ According to the README.namelist, you can run without any LSM by setting sf_surface_physics to 0, which implies no surface temperature evolution. So the absolute minimum is probably nothing. Slab sounds like a reasonable starting point to me. $\endgroup$– milancurcicCommented Apr 20, 2018 at 14:41

$\begingroup$ @milancurcic thanks! so the slab model would be a sensible step to move on with. $\endgroup$– sunt05Commented Apr 20, 2018 at 14:53
