1. Core Problem
Running WRFDA 3DVar:- xb_date (fg file time) = 2025-08-01_00:00:00 (correct, program recognizes fg file)
- an_date (analysis date) = hardcoded 2002-08-03_00:00:00 → fatal time mismatch error (da_setup_firstguess_wrf.inc LINE 49)
2. Environment
- System: Ubuntu (VMware), WRFDA 3DVar (var4d=.false.), MPI parallel (dmpar)
- Only namelist.input in run dir (backups moved, no Windows line breaks via dos2unix)
- MPI/env/permissions all OK (program starts normally, no MPI_ABORT)
3. Failed Fixes
- Added analysis_date='2025-08-01_00:00:00' in &wrfvar
- Split time params in &wrfvar: analysis_year=2025, analysis_month=8, analysis_accu=0 (no leading zeros)
- Aligned &time_control start time with fg file (start_year=2025 etc.)
- Verified &wrfvar module is unparsed (custom tag not in logs)
