Summary of Diagnosis

Codes of diagnosis for DFI have been added and tested with both single-threaded and MPICH options on platform of CrayXE1.

1. How to generate DFI Diagnosis files?

A. Download wrfdfi_20060417.tar.gz to wrf working directory from WRF DFI homepage.

B. Unzip and untar the file.

C. cd WRFV2

D. ./configure

E. compile em_real

F. ls –l main/wrf.exe

2. How to run WRF-Diagnosis?

A. Download runwrfdfi.gz to WRFV2/test directory from WRF DFI homepage(A small grid for testing).

B. Unzip and untar the file.

C. cd runwrfdfi

D. vi namelist.input

E. Setting namelist options

To get ‘SFCEVP’ : sf_surface_physics = 2

To get ‘DIV’ : diff_opt = 1 or 2, km_opt = 2 or 4

F. ./wrf.exe

3. How to confirm the results?

A. Download rip_diag.tar.gz to runwrfdfi directory from DFI WORK homepage.

B. Unzip and untar the file

C. mv fields.f to RIP/src

D. cd RIP

F. cd runwrfdfi

G. ./wrf_dfi_grph.csh

H. idt image_filename

B. ./dyn_em

solve_em.F: add ‘call subroutine’ for diagnoses

module_big_step_utilities.F: add subroutines to calculate for diagnoses

C. ./phys
