D11. System
design.
D12. WRF model and 3DVAR codes, test cases and
documentation:
(1)
wrfsi program: wrfsi
code ,
(2) wrf model program: wrf code ,
(3) 3DVAR obs preprocessor program: 3DVAR_OBSPROC
code
(4) WRF 3D-Var program: wrfvar
code .
The wrfvar code were updated with
bugs fixed and two more functions: QC-OBS and VERIFY
(refer to http://box.mmm.ucar.edu/people/guo/individual_guo/CWB/CWB_Project_2006.html
, section Data assimilation)
NMC_Stage0_for_WRF: ducument.
A simplified gen_be_Stage0 code for both MM5 and WRF
regional models has developed
and intensively tested in PC Linux by Yong-Run Guo
(NCAR),
Shui-Yong Fan (BMB), and
Hui-Chuan Lin (CWB). The new code can be downloaded
from gen_be_Stage0.
(5) update BC program: WRF_BC code ,
(6) terrestrial data for wrfsi: Terrestrial
Data.
D13. A BMB
local data set.
Case_710_data_detail
D21. Modified code.
D22. System design (version 2).
Single_OBS_test
Semi-annual review presented by Hans Huang at BMB, Beijing, December 2005 (ppt file).
D23. Report on assimilating BMB local data.

WRFVAR-based verification
This verification package
is composed of wrfvar code, RMS/Bias errors computing and plotting
program, and two utility
programs:
The time advancing program: advance_cymdh.f90
WRF forecast file
splitting program: wrfout_split
wrfvar code is same
as above in D12 (4)
RMS and Bias errors
computing and plotting program: plot_var_stats and the scripts
After untarred Verify_scripts.tar
downloaded by click scripts, please
read README file carefully
to learn how to
use this wrfvar-based verification package.
