When running the script, no error is reported, but the LUFRAC\_CRO file does not appear. Other files are generated normally, and there is no error in the log. Why is this? This is the script I ran and the log generated  
[run\_mcip.cn12.csh](https://forum.cmascenter.org/uploads/short-url/wTEgshgK3F1kkP1MOXGclBPIMIZ.csh) (21.7 KB) [run.cn12.log.txt](https://forum.cmascenter.org/uploads/short-url/7W8DJqmZxKNvEECMiNJ2pAJZepa.txt) (549.0 KB)

The log file contains the following output:

* * *

\*\*\* SUBROUTINE: SETUP\_WRFEM  
\*\*\* DID NOT FIND FRACTIONAL LAND USE IN wrfout  
\*\*\* AND DID NOT FIND GEOGRID FILE  
\*\*\* – WILL NOT USE FRACTIONAL LAND USE DATA

* * *

LUFRAC\_CRO is only created if it fractional land use data is available in WRF or in GEOGRID.

Hi @zhuy!

I suggest you open this as a new issue/new thread on this Forum. In doing so, please add whether you have fractional land use (LANDUSEF) available for MCIP either in your wrfout or geogrid files.
