    Dear WRF users,<br>
    <br>
    Can anyone please tell me what SQVISC is, what unit it is in and
    where this constant comes from?<br>
    It is, I suppose, the square of the viscosity of air, based on Cheng
    and Zhang 2009 and how it is used in the code, but I cannot work out
    which unit it is in.<br>
    <br>
    module_sf_noahmplsm.F<br>
    REAL,    PARAMETER :: SQVISC = 258.2<br>
    <br>
    It is also used here:<br>
    module_bl_myjpbl.F:     &                
    ,SQPR=0.84,SQSC=0.84,SQVISC=258.2,TVISC=2.1E-5   &<br>
