    wrfoutReady files are not written when using IO Quilting

    It appears as though the wrfoutReady files are not written when running WRF version 4.4.0 and using IO quilting. Is this the expected behavior? &time_control output_ready_flag = .true., &domains nproc_x = 15, nproc_y = 21, &namelist_quilt...

    SST update delayed by one history interval in wrfout_d02

    Hi, I am preparing a multi-year WRF simulation and need to update SST. I am not using an external SST dataset but want to update SST from ERA5 data, which is used as model input at the same time (I therefore did not run ungrib.exe twice to create separate ‘SST’ files for metgrid). ERA5 driving...

    real error - Segmentation fault - Runs for One type for physics but not Another

    I have been trying to run ERA5 data (single levels and pressure levels) for the past 2 weeks, but unsuccessful in real.exe for one physics suite but not for another. Idont understand where i am wrong. The error i encounter is as follows: taskid: 0 hostname:

    WRF-SCM Forcing with Reanalysis Data

    Hi, I am new to WRF-SCM and I am having a couple of trivial questions regarding the forcing input file in the Single Column Model. My first question is whether the forcing inputs can be provided from any readily available reanalysis datasets. If yes then how can the geostrophic components of...

    Tables in WRF/test/em_real

    I am trying to understand how the tables in WRF are used (The tables located in em_real, such as LANDUSE.TBL and URBPARM.TBL). Under what circumstances does WRF use these tables (what settings need to be turned on)? Where in the flow of WRF are the tables used? Is there documentation for the use...

    WRF and WUADPT

    Hi, Sir, We are using WRF V4.3.3 MODEL with WUADPT LCZ level 0 classification, the LCZ classification requested from the LCZ generator to classify the study region. Then we provided data into the using the python script. After that, all the steps follow the as same in normal wrf...

    Hi all, I am very new to WRF. I am trying to simulate an idealized LES case similar to the test case in WRF. When I observe data for PBLH, I see all 0s. Does WRF-LES calculate PBHL? Do I need to modify anything in the namelist.input to get this done? Any input would be greatly appreciated...

    Running WPS with CFSV2

    Has anyone experienced using WRF with CFSv2 downloaded from RDA? My concern is when we choose WRF-prescribed input, the fields are 6-hourly forecast when our need is the analysis. However, the soil-related fields (i.e. volumetric soil content) are not available in the 'analysis' but they are...

    WRF running very slow after new compile

    Hello all, I recently had to recompile WRF because the HPC environment I run WRF on had its OS updated which caused many files WRF depended on to be updated and renamed. I created a thread on this issue and it can be found here.. While I was able to successfully recompile and run WRF, it now...

    Fails to run with two nested domains but ok with single nest

    Dear altruists, I am trying to run ./real.exe using 3 domains of 20 km, 10 km & 5 km. It stops at the middle by showing "Full level index = 34 Height = 19871.2 m Thickness = 920.1 m". But simulation can be done successfully with 2 domains. The same thing happens with domain resolutions such as...
