I have a WRF simulation with output time interval = 30.0 min, and I am running MCIP and would like to the output has 60.0 min time interval. I set INTVL = 60 in the MCIP script but the issue came up with:  
\*\*\* SUBROUTINE: SETGRIDDEFS  
MCIP output interval cannot be shorter than input  
User-defined MCIP output interval = 60  
Meteorology output interval = 30.0

* * *

```
 *** ERROR ABORT in subroutine SETGRIDDEFS
 ABNORMAL TERMINATION IN SETGRIDDEFS
 Date and time 0:00:00 July 2, 2018 (2018183:000000)

```

As it said, MCIP output should not shorter than input, I think my setting is reasonable. Is there anyone know how to solve this issue?  
Thanks!

Please try this:

> 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 The error US EPA COMMUNITY MULTISCALE AIR QUALITY MODEL METEOROLOGY-CHEMISTRY INTERFACE PROCESSOR MCIP V5.1 FROZEN 11/21/2019 ==================…
