Good afternoon Yi-Chuan,

The fhlwr and fhswr variables do control the calling frequency for the longwave and shortwave radiation based on the radiation scheme of the CCPP suite you are using. These variables are similar to the radt variable in WRF, with the exception of radt controls both shortwave and longwave radiation calls and is defined in minutes instead of seconds.

Please let us know if you have any additional questions.

Thanks!
