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...

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...
