  • Hi, I tried to use open ECMWF data for forecasting and GFS data to fill in the missing data, I used pywiner to generate the WPS intermediate file for ECMWF, and metgrid.exe multi-source runtime to generate the met_em* file containing both GFS and ECMWF, why is it that the vertical layer of the generated met_em* file is 34 layers? Looking forward to your answer!
    I need information regarding the MPAS model with the passive tracer experiment and have seen your methodology to initiate the new input in the MPAS model to compute and see the transport with the regional scale of this initialization. I treat any local GHG traces for CH4 as a simple passive tracer without looking at any chemistry thing. If you have any ideas. Can you help me with this? Please let me know. Thanks
    I am new to running WRF-Chem. I want to know how different WRF-Chem v3.7.1 and v 4.4. are. Are there any reference about it?
    Hello! I ran into problems when running the Marine module in wrf. I set the parameter sf_ocean_physics = 1 and changed the parameters of mixture layer thickness and temperature lapse rate (oml_hml0 and oml_gamma). However, it is a pity to find that sst does not change during operation. May I ask what causes this and is there any good solution?
    I have also tried replacing the original data in WPS_GEOG using the convert_geotiff method, but I get the message "WPS_GEOG/lu_index/00001-00200.00001-00200, point (748, 214) has an invalid category of 0". However, the lu_index in the generated geo_em data has been successfully replaced, but LAI and others remain as 0. Do you have any suggestions? Thank you very much, and I look forward to your reply.
    Hello, I would like to replace the LAI, ALBEDO12 and LU_INDEX in WPS with another dataset. I have adjusted the data format to match WPS, but when I modify and run metgrid.exe, I get the error "ERROR: In read_next_field(), problems with ext_pkg_get_var_info()". If I modify met_em*, I can run real.exe, but when I run wrf.exe, I encounter a segmentation fault.
    hello, please assist with selecting the proper domain for my simulation. I managed to install Dwiz and its working perfectly i can even do WPS with it. I wish i could attach a file so that you appreciate as well.
    Due to my LAI's tif data having 12 bands, I am currently using gdal_ Translate cannot convert tif to bil format correctly. How should I replace LAI data in WPS?

    Looking forward to your reply, thank you!
    Hello, I see your answer to this error: ERROR: Ran out of valid boundary conditions in file wrfbdy_d01. At present, I have encountered the same question. My start date is 2010-11-14-00-00-00 and end date is 2010-11-22-18-00-00. According to your answer, I set run days is 8 and run hours is 18. But my wrfbdy's end date is still 2010-11-22-12-00-00.
    I do not know what data to download to use ECMWF (ds626.0) as initial and boundary condition at pressure levels and surface.
