Hi All
I encountered two errors while running the CMAQ/mcip section, as follows:

Plese hellp me
Thanks!

Here is the error message that you shared a screenshot of.

Error running mcip

Excerpt from the run_mcip.csh that you shared:

#-----------------------------------------------------------------------
# Set CTM layers.  Should be in descending order starting at 1 and
# ending with 0.  There is currently a maximum of 100 layers allowed.
# To use all of the layers from the input meteorology without
# collapsing (or explicitly specifying), set CTMLAYS = -1.0.
#-----------------------------------------------------------------------

#set CTMLAYS = "-1.0"
 set CTMLAYS = "1.000, 0.998, 0.99, 0.985, 0.98, 0.97, 0.96, 0.95, 0.94, \
               0.93, 0.92, 0.91, 0.9, 0.88, 0.86, 0.83, 0.8, 0.77, 0.74, \
               0.71, 0.68, 0.64, 0.6, 0.56, 0.52, 0.48, 0.44, 0.4, 0.36, \
               0.32, 0.28,0.24, 0.2, 0.16, 0.12, 0.08, 0.05, 0.000"

I am not sure what version of MCIP you are using, but current versions do not support using different layers than what is available from the WRF model output.

Please try using this option instead.

set CTMLAYS = "-1.0"

In addition, please consider downloading the latest versions of CMAQ and MCIP.

# Meteorology-Chemistry Interface Processor (MCIP)

The Meteorology-Chemistry Interface Processor (MCIP) ingests output from the [Weather Research and Forecasting (WRF) Model](http://www.wrf-model.org) to prepare the meteorology files that are used within the CMAQ Modeling System. Where possible, MCIP uses data directly from the meteorological model to maximize consistency with the CMAQ Modeling System. When specific atmospheric fields are not explicitly output by WRF, MCIP uses scientific algorithms to create those fields for CMAQ.  MCIP output is used by the emissions model (for example, to provide time-varying temperatures for mobile emissions) and by the CCTM to define the atmospheric conditions. A scientific overview of MCIP is in [Otte and Pleim (2010)](https://www.geosci-model-dev.net/3/243/2010/).

MCIP performs the following functions using the output (history) file from WRF:

-   Defines the computational domain for the CCTM. The CCTM typically uses a smaller computational domain than the meteorological model, and the lateral boundary cells from the meteorological model generally are not used by CCTM.

-   Extracts meteorological model output on the computational domain that is prescribed for the CCTM.

-   Processes all required meteorological fields for the emissions model and the CCTM. Meteorological fields such as atmospheric temperature, pressure, humidity, and winds are acquired directly from the meteorological model (i.e., "passed through").

-   Uses the available meteorological fields to compute additional fields that are required by the CCTM but are not part of the meteorological model's output stream, such as the Jacobian which is used for coordinate transformations.

-   Outputs files that contain meteorological and geospatial information used by the emissions model and the CCTM.  The output can be either in I/O API or netCDF.

MCIP is written in FORTRAN, and it runs on a single processor in a Unix/Linux environment. MCIP is driven by a C-shell script with several run-time options that are defined through a FORTRAN namelist. It is typical to use MCIP to process hourly output fields from the meteorological model for each one-day period.

MCIP is often updated concurrently with the CCTM.  The changes to MCIP are documented with each update to the software, and a "Frequently Asked Questions" (FAQ) file exists that is specific to MCIP.

Thanks for your reply！
I am currently using CMAQv5.2. I used the MCIP module in CMAQv5.2 to process WRFOUT. I set CTMLAYS = “-1.0”, then run run_mcip.csh again, and Unmatched as shown in the first figure appears. What is the cause of this problem? Please hellp me, thanks!

Please verify the contents of the log file. Prior to running mcip again, also delete any mcip output that was previously generated.
