WRF-Chem could not find matching time in wrfchemi_ for new day


New member
Hi all, new WRF-Chem user and first time poster.

My three day, four nested domain simulation runs for the first 24 h (2023-02-22), then fails to move onto the next day, with the following error.
ERROR: Could not find matching time in input file wrfchemi_d01_2023-02-22_00:00:00

It should be going on to the next day, 2023-02-23, but seems to be looking for 2023-02-23 00:00 emissions in the 2022-02-22 00:00 file instead.
I suspect I have a namelist setting wrong but am struggling to find online documentation for the auxinput5 settings.

I have daily wrfchemi_d0* files, each with 24 hrs of data in them. They are in the run directory. In namelist.input I have set:
auxinput5_inname = 'wrfchemi_d<domain>_<date>'
auxinput5_interval_h = 24, 24, 24, 24
frames_per_auxinput5 = 24, 24, 24, 24

I have attached namelist.input and rsl.error.0000. Any help or suggestions greatly appreciated!

May be you can add the following settings instead of yours.
auxinput5_inname = "wrfchemi_d<domain>_<date>",
auxinput5_interval_m = 60, 60, 60, 60,
io_form_auxinput5 = 2,
frames_per_auxinput5 = 1,1,1,1,
