Hello everyone: When I was working on the cycle mode of WRFDA, I conducted data assimilation at 0:00, 6:00, 12:00, and 18:00 respectively. I found that after completing the assimilation at 6:00 and linking to the WRF running directory, the namelist should be integrated from 6:00 to 12:00...

While compiling WRFDA only 10 executable was created from 44 executable. The configuration was successful using gfortran but while compilation all the executable were not formed. The main error found was- make[1]: [da.make:167: da_wrfvar.exe] Error 127 (ignored). I'm attaching compile.log file...

Good day, I want to compile WRFDA by following this tutorial: Chapter 6: WRFDA. I am able to compile and build all of the executables, except for the da_wrfvar.exe. Upon looking the compile logs, the reason is this line (and variations of it): da_wrfvar_top.f:4223:101: 4223 | real...

I am trying to install wgrib2 on ubuntu 20. After defining CC=gcc, FC=gfortran, then I type make. I get the error: makefile:241: *** need fortran-95+TR-15581/fortran-2003 compiler, not f77. Stop. Can I edit the makefile to put f90 on the indicated line 241 instead of f77?

When I assimilate the AHI data on WRFDAV4.4, I get a memory error, but when I assimilate it at another time, it works fine, and I have re-downloaded the data several times with the same problem. According to the output of the rsl.out file, the program ended at the time of the VARBC. I would...

Hello, I am trying to compile the data assimilation routines available in WRFDA. I have successfully compiled WRFPLUS, but I get several errors when trying to compile WRFDA (./compile all_wrfvar). In particular, I get errors of the form: ./libwrfvar.a(da_netcdf_interface.o): in function...

Good morning, So I saw this in the release notes for 4.4.1 Just so I understand correctly, this means that WRFDA and WRFPLUS functionality are now enabled for WRF-CHEM? I want to include them in my scripts but I don't want to add them if they are not truly functional.

Good morning I am trying to use obsproc or obsgrid to nudge my wrf run with metar data. But metar data is in ascii and it needs to be in little_r. I don't have any programming language experience to do this. Does anyone have a script in any language or programming code that does this?

Hi All, I am trying to compile WRFDA and am running into issues. We are using the PGI compiler. WRF and WRFPLUS compile successfully, but the process always ends with an error for WRFDA. I was hoping someone had some idea of what could be going on. I have attached my compile log to the post...

Good afternoon, I am wondering if you can compile WRFDA 4DVAR in parallel? I can compile and make all the other WRF code in parallel but when I do 4DAR in parallel it gives some fatal errors. Is WRFDA 4DVAR not parallel enabled? My code that I am using is this: Where $CPU_HALF_EVEN is half...

Dear Wrf Community, I have tried to compile WRFDA4.4 after succesfully compiling WRF/WPS4.4 with intel ifort. I have a problem in compile that it seems related to a sintax error with module_configure.f90, module_domain.f90, module_nesting.f90 (all f90). Part of log: /lib/cpp -C -P -traditional...

Hello, Following the instructions here I've built zlib (1.2.12), HDF5 (hdf5-1.12.0) and trying to now build NetCDF (4.8.1) but during the configure I'm getting a message that hdf5_hldll can't be found. Does anybody know if there is a way to 1) Have NetCDF not require this library or 2) Build...
