RIBX never exceeds RIC, RIB error

Hello,

I'm trying to run a cycled forecast using WRFDA and WRF. I am cycling the forecast every 3 hours, and I'm using the ACM2 PBL and the corresponding sf schemes (all option 7). When I run WRF normally without any assimilation, I do not run into this error

-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 415
RIBX never exceeds RIC, RIB(i,kte) = 0.00000000 THETAV(i,1) = NaN MOL= NaN TCONV = 1.35631564E-19 WST = NaN KMIX = 49 UST = NaN TST = NaN U,V = NaN NaN I,J= 1 1
-------------------------------------------

However when I run it using the wrfvar_output generated from WRFDA, I get the above error. I have attached two separate rsl files. The no_WRFDA_rsl.out.0000 file is from the WRF simulation that did not use the wrfinput generated from WRFDA. The second file (WRFDA_rsl.out.0000), is the file that contains the crash when I move the wrfvar_output to wrfinput_d01. I have also attached both namelist.input files. Keep in mind the debug level was set to 100, so there is more information than usual. Do keep in mind these rsl files are from different simulations, and I stopped the simulation that did not use WRFDA. I will keep trying to figure this out in the meantime, but any advice would be greatly appreciated.

The first cycle ran without a problem (I was able to create a wrfvar_output and run WRF), however this just started happening on the second cycle where I'm reinitializing the wrfout_d01_03 to observations and attempting to create a new wrfvar_output.

Thanks,
JeremyB

I believe this was an issue with the PBL scheme. I never did find the solution to this except for changing PBL schemes.
 
Our DA expert says that he never used ACM before and he has no answer to this issue, ---- I am sorry.

Hello Ming Chen,

No worries. I really appreciate you going out of your way to ask them. I suppose this should be an issue on the github then? If I do ever figure this out I will be sure to update this post. Again thank you for your time.

Thanks,
JeremyB
