Deliverables:
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).

Progress report to Director Wang at NCAR, 28 June 2006, presented by Yong-Run Guo (ppt file).

D23. Report on assimilating BMB local data.
BMB Observation network: 4 Wind profilers, 9 GPS and 48 AWS.

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.

D31. A WRF based data assimilation system for BMB.

Report from Shui-Yong Fan (Summary of verification, Beijing, 23 March 2006) (ppt file)
Report from Shui-Yong Fan on 9-km WRF Exps, Beijing, 14 July 2006 (doc file)
Report from Shui-Yong Fan for WRF model tuning (SILAVWT=0, 1, 2,3 in WRFSI), 31 JUly 2006 (ppt file).
Report from Shui-Yong Fan about new WRF mode configuration (10 August 2006) (doc file).

Report from Jiqin Zhong (Summary of work, 20060323) (ppt file)
Report from Zhong (OSE for 27-km domain), 20070323 (pdf file)

D32. Report on AWS data impact.
D33. Report on GPS-PW data impact.

        Report from Jiqin Zhong for Beijing GPS PW impact (April 2006) (ppt file)

D41. Report on computational performance.

        Shui-Yong Fan and Jiqin Zhong gave a detailed report of WRFVar and WRF model (doc file) running in BMB AMD Opteron machine.
        From this report, the computational performance  can meet the operational requirements. The main problem is  that  9-km  WRF model run  gave significantly negative bias of the surface temperature forecast in compared it with the MM5 forecast.

 
D51. Report on implementation of WRF data assimilation system at BMB.
D61. Report on pre-operational trials.

    Main work is to implement the WRFVar/WRF performance tuning for BMB operational. As the first step, the WRF model was tuned, and
    the report (pdf file)  have been posted here.

    report (pdf file) on 20070406.

D71. Report on the operational performance.
D72. Report on case studies.

    Shui-Yong Fan conducted a series of the experiments for "01 August 2006" squall-line case with 1-h and 3-h cycling mode and
    a variety of the var_scaling tuning for 27/9/3-km nested domains. The report can be found from Report (pdf file) on 20070420.

    Report (pdf file) on 20070525.

D73. A WRF based data assimilation system which could be used to support the BMB meteorological service during Beijing 2008 Olympics.
