filtered files in WRFDA

Hi, I am trying to familiarize myself with radiance data assimilation within WRFDA. Does anyone know what the auxiliary files WRFDA writes in output, named filtered_*.0001, filtered_*.0002, etc, are? I can't find any reference about them. They seems to be binary files and I do not see any of the scr...

Assimilating radiances from NCEP gdas files

Hi Everyone, I am trying to assimilate the ATMS radiances into my WRFDAv3.9.1 over Hawaii from the NCEP file: gdas.t12z.atms.tm00.bufr_d linked to atms.bufr In the namelist I have: &wrfvar18 analysis_date="2020-10-15_12:00:00", / &wrfvar19 / &wrfvar20 / &wrfvar21 time_window_min="2020-10-15 10:24:00...

GEN_BE on Cheyenne

Hi, I would like to create a BE matrix to use for our WRFDA set up. I did this before on a local cluster, but I have now access to Cheyenne and would like to use the parallel capabilities of the gen_be scripts. My understanding is that the gen_be_stage4_regional.ksh script uses the bsub command with...

adaptive time stepping; run ends before time

Hi, When I run WRF with adaptive_time_step set to .true, there are times when the WRF run ends prematurely, either at the very beginning or at some point before the defined end of simulation time with the regular message: Timing for main (dt= 0.00): time 2015-04-23_03:00:00 on domain 1: 3.58631 elap...

Run fails with Adaptive time step in cycling mode

Hi, I am running WRF (v3.9.1) in cycling mode (every 6 hour) using WRFDA on a previous 6h WRF forecast as background. I normally use adaptive time stepping, to save on simulation time. If I run WRF in cold mode, it works just fine. But if I run WRF every six hour, using previous 6h forecast as backg...

domain index into parameterization

Aloha, Is anyone aware of a way to get info on the running domain ID within the module_pbl_myjpbl.F routine? Is the domain ID accessible within this routine (I could not find it), or do I need to pass it as a new argument? I need to have the info on the running ID, that is whether is the coarse or n...
