Project: 

  Incorporate CLM into WRF

Mission:

  Incorporate CLM as a land model component in WRF.

Goals:

  Create a new WRF-CLM interface analogous to the CAM-CLM interface
  that will permit CLM to run a land model component in WRF.

  The following initial constraints will be assumed:

    - CLM will run in the WRF decomposition (no redistribution will take place)
    - A new communicator will be created so that CLM will only run on
      MPI processes that contain at least one land gridcell in the WRF patch
    - CLM will use the WRF ESMF clock
    - All WRF-CLM communication wil take place in a interface module
      clm_wrfMod.F90
    - WRF will pass to CLM the declination angle to be used for the zenith
      angle computation

Motivation:

  The ability to use a CCSM component within WRF is highly desirable for
  both CLM and WRF.

Authority:

  Mariana Vertenstein 

Project Lead(s):

  Mariana Vertenstein (CSEG) and Tom Henderson (WRF)

Implementation Plan:

  Stage 1) Have CLM and WRF run for a model day and produce "reasonable results"
           CLM will start from arbitrary initialization.
           CLM will start from a surface dataset that is determined offline.

Resources and Schedule:

   
              ============
     Mariana  1 person-month
     Tom      1 person-month
     Total    2 person-months

     Total effort: ~2 person-months
     Stage 1 is scheduled to be completed on March 22.
