Hi anyone or @tlspero  
I am getting the error that MCIP cannot produce outputs at temporal resolution coarser than the input meteorology data. Is it intentionally a feature of the MCIP or a bug? (I saw some past post similar to this but that was related to WRF time step being too coarse) Thank you

@CMAQ_user –

I believe this is a bug in MCIP. To correct this problem, please edit line 539 in setgriddefs.f90 so that it reads:

IF ( intvl \< NINT(met\_tapfrq) ) THEN

Please let me know if this works for you. If so, I’ll correct it in the next release of MCIP.
