al. 2007 , 2016 ). Surface radiative cooling is closely related to the surface energy balance, which is composed of incoming and outgoing radiation and heat fluxes in the atmosphere, canopy, and soil. The complexities involved in the calculation of fluxes are substantial, especially in the case of radiation fog or ice fog. In numerical models, the parameterization of the surface energy balance is strongly related to the parameterizations of both the land surface and boundary layer. Specifically

GM are approximately 20°C, precluding the need for alternative grid methods such as those described in Lundquist et al. (2012) . Physical parameterizations include the Lin et al. (1983) microphysical scheme, the RRTM longwave radiation parameterization ( Mlawer et al. 1997 ), the Dudhia shortwave radiation parameterization ( Dudhia 1989 ), and the quasi-normal scale elimination (QNSE) planetary boundary layer (PBL) scheme ( Sukoriansky et al. 2005 ). The model also included the improved land

effect that clouds have on the SEB components, following Massey et al. (2016) , we delineate mostly clear and mostly cloudy days during the MATERHORN periods using atmospheric transmittance, defined as with SW sfc ( t ) being the observed downwelling shortwave (SW) radiation at the surface at time t and SW toa ( t ) being the theoretical downwelling top-of-atmosphere SW calculated from where S 0 is the solar constant (approximated to be 1370 W m −2 ), a is the annual mean distance between the
