DESCRIPTION OF CHANGES

WRF-TEB (Meyer et al., 2020a) couples the single layer Town Energy Balance (TEB) model (Masson, 2000, and subsequent papers) model, software (Meyer et al., 2020b), to the Weather Research and Forecasting (WRF; Skamarock et al., 2019).

This PR includes all the files modified in WRF as well as the wrapper for TEB phys/module_sf_teb.F used to integrate TEB model (https://github.com/teb-model/teb) as an external library into WRF.

The implementation here reflects what is in Meyer et al., 2020a with WRF-CMake (Riechert and Meyer, 2010). The entry point for TEB is phys/module_sf_teb.F which calls src/driver/modd_wrf_teb_driver.F90 from the TEB model repository https://github.com/teb-model/teb. Information on how to install and run WRF-TEB are included in external/teb/README.md.

TESTS CONDUCTED

TODO -- @davegill I have already carried out tests and I will update this but please clarify if you want bit-for-bit identical output files in which case we would need remove the following from history/have them on only when TEB is enabled.

@dmey @dudhia @weiwangncar @barlage
Since this is a new physics option, this code will need to go through the Physics Review Board.

@dudhia @davegill @weiwangncar @barlage should I go ahead and send a letter of intent (LOI) to the Physics Review Panel (PRP) (e-mail: wprp@ucar.edu)? It looks like the statements on the LOI are a subset of those in the paper already. Else we could simply share the the paper/summary of it as it includes more.

@dudhia @barlage @weiwangncar
Folks,
It has been 5 months. Any movement from the physics review board?

What does "external library" mean? Is this a separately compiled set of files that produce a Unix library file? Is this just a way of referring to a traditional subroutine call?

[dudhia]

We pushed it off till after the release, so now is the time to get back to this on the WPRP.

@davegill a library dependency similarly to what is already done with other external libraries such as libnetcdf. TEB is therefore installed first on the system and then linked against if the user wishes to use the coupled WRF-TEB. I have detailed this more fully in section 4.1 in https://doi.org/10.1029/2019ms001961. Actual installation instructions on how to do this are in external/teb/README.md.

[dudhia]

Yes, the build is certainly different, and we would like an explanation of why it can't be done similarly to the other physics in WRF, Jimy

Section 4 -- Software Implementation -- should explain.

[dudhia]

OK, we can ask Dave for his expert opinion on that or any questions he has. Thanks, Jimy

@dmey Do you have an interest to incorporate TEB urban model to NoahMP? I'm asking this since going forward most development on the land model will be on NoahMP.

@weiwangncar I was not planning to do this. I am also not familiar with the NoahMP code but if you can spare some help, maybe this is something that we can plan for a separate PR?
