Intercomparison of Radiation Codes in Climate Models Phase III Assessing the Interpretation and Handling of Clouds by 1D Radiative Transfer Algorithms Part I: Solar Radiation Howard W. Barker (1), Philip T. Partain (2), and Graeme L. Stephens (2) (1) Cloud Physics Research Division, AES, Downsview, ON, Canada (2) Dept. of Atmos. Sci., Colorado State Univ., Ft. Collins, CO, USA       The main purpose of this study is to assess how well 1D solar radiative transfer codes, especially those used in NWP models and GCMs, interpret and handle unresolved clouds. This will be achieved by first doing Monte Carlo simulations on 3D atmospheres simulated by cloud-resolving models (CRMs) and then passing corresponding profiles of cloud properties to 1D radiative transfer codes.
