I am running WRF-Chem v4.5 to forecast PM2.5 using chem_opt = 106 in namelist.input. For boundary and initial conditions, I am using WACCM data from 2024.something old data since newest data is not available .

However, during the mozbc processing, I encountered the following error:

get_moz_time_ndx; wrf_date, wrf_datesec, ntime_m = 20250130 0 33 next_flnm; trying to increment file waccm-20250121031747210764.nc next_flnm; il, iu = 7 26 next_filenm: failed to read 20250121031747210764 ; error = 5010

I understand that this error occurs because my WACCM dataset does not cover the forecast period (2025-01-30 to 2025-01-31), leading to a time mismatch.

Could you please guide me on how to generate the boundary and initial conditions for the WRF-CHEM model forecast  using the mozbc tool.or using the WACCM data or CAM-CHEM data .

Looking forward to your suggestions.

thank you
