Hi,
I need help to solve my issue.
I am using WRF version 3.8 and trying to run WRF in 2018 using FNL data.
But, I see this error just right after starting the run:

d01 2018-01-01_00:00:01 SST_UPDATE is on
d01 2018-01-01_00:00:01 in PX Surface Layer scheme
d01 2018-01-01_00:00:01 in P-X LSM
d01 2018-01-01_00:00:01 call pbl_driver
d01 2018-01-01_00:00:01 in ACM PBL
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 443
RIBX never exceeds RIC, RIB(i,kte) = 0.000000 THETAV(i,1) = 272.4925 MOL= -2.2714128E-16 TCONV = 3.8857731E+08 WST = 10981.45 KMIX = 35 UST = 1.1146363E-02 TST = -3.7922863E+13 U,V = -1.838400 1.071798 I,J= 142 100
-------------------------------------------

The grid point at (142,100) is a land next to ocean grid, but it doesn't have high terrain height.
I tried to use much shorter time step and it didn't work even I decreased it as 1.
I attached my wrf namelist.
I know this issue is related to ACM2 pbl scheme, but I don't know how to deal with it.
Please let me know if you have any idea on what could solve it!!

All the Bests,

Hi,
I am not sure how this post got overlooked, but I just found it when searching. Were you able to solve this problem?

This error is caused by unreasonable input data. Can you use WPSv3.9.1.1 or newer version to process FNL, then try again? You can still work with WRFV3.8 even if you run newer version of WPS. Please let me know if you still have the problem.

Okay. Let me try with newer version of WPS.
Thank you!

Dear Chen,

My problem has been solved by using WPS version 4.0 (then I use WRF3.8).
Thank you for your help. :lol: :lol: :lol:
