WRFDA-4DVar is stopping in between !!!

Postby deejeek » Fri Jul 06, 2018 9:05 am

Dear WRF users

I am using WRFDAv3.8.1. I was doing 30 days continuous cyclic assimilations at 12h interval using 4DVar. For first 11 days (ie, 24 cycles) it worked smoothly. For the analysis for 12th day, DA got stopped. I could not find any error in rsl files also. I was using 12h (wrf) forecast from previous cycle as fg. But, if I replace fg with the wrfinput_d01 (which comes out of real.exe), this will work.
The error message is as follows:

Calculate innovation vector(iv)

---------------------------- FATAL ERROR -----------------------
Fatal error in file: <A HREF="http://www.mmm.ucar.edu/people/wrfhelp/wrfvar/code/trunk/da_wrf_tpq_2_slp.html">da_wrf_tpq_2_slp.inc</a> LINE: 69
Cannot find pressure level 10000.000 Pa above the surface
PL= 90447.710 PSFC= 100447.710
----------------------------------------------------------------

I would be grateful, if anyone can help in sorting out this.
Thanks,
deejeek
