This PR is a bug fix when calling the Thompson parameterization of the cloud fraction. This bug was first brought to our attention by Brett Wilt back in February 2022 but never corrected in subsequent bug fix releases.
The input to the Thompson scheme is expecting the grid scale to be in units of km, but in mpas_atmphys_driver_cloudiness.F source, dx_p is in units of meters. The unit of dx_p has been corrected to be kilometers.
