wrfda compiling/installation

Hi all, I’m currently running gen_be_v3 in WRFDA to generate background error statistics, and I would like to better understand the outputs. After running, I obtained the following types of files for multiple variables (e.g., PSFC, T, RH, U, V, W, QCLOUD, etc.): be_*.dat EV_*.dat Bv_*.txt...

I am working with WRFDA v4.5.2, attempting both 3DVAR and 3DEnVar. I was able to successfully generate a background error covariance matrix using the NMC method, as well as ensemble perturbations from multiple HRRR-initialized WRF members. For observations, I sampled composite radar...

Hello everyone, According to the WRFDA user guide, it appears that only RTTOV version 12 is supported. Could you please confirm if there is any version of WRF that is compatible with RTTOV 13? Any insights or suggestions would be greatly appreciated.

Hello, I am currently trying to run nested grids within WRF while using WRFDA. The user guide isn't too helpful on this subject, and because of the required naming conventions I was wondering if there was a way to also assimilate into the child nest. Or, does it really not matter? Can I...

Dear all, We are in the final process of evaluating our new scheme for data assimilation (DA) applied to the WRF model. We need to do a comparison for computer processing between our method and other DA methods already available in the WRF. Can you help us indicate which WRFDA code part is...

I have been trying to solve a bug with WRF Plus installation for the ./configure_new script. I have set WRF_ROOT from my build of 4.6.1 and I was successful in installing WPS using ./configure_new My commands are these that I used for WRF PLUS [workhorse@localhost WRFPLUS]$ ./configure_new...

Hi, I am trying to compile WRFDA with 4d var capability. I have compiled both RTTOV and WRFPLUS prior and gave appropriate path before compiling WRFDA. Almost all the executable are generated but da_wrfvar.exe. I am providing the log files along with this. Is this issue related to either RTTOV...

Hello everyone, I currently use WRF (Weather Research and Forecasting) for my simulations on a Windows laptop x1 yoga with an Intel i7 (8th generation) processor. I'm considering purchasing a MacBook Pro with the M1 chip to potentially benefit from better performance. Before I make the switch...

Hi I have WRF4.5.2 which I have installed and run successfully. Now I want to run some test with WRFDA and I am following the installation from this link Chapter 6: WRFDA Initially, compilation seems to be ok, but when I check the .exe files, I'm missing one (the most important da_wrfvar.exe)...
