Abstract While most of models participated in CMIP6 do not consider precipitating ice (snow) radiative effects (NOS), there are several models implement prognostic snow in addition to cloud ice separately (CESM2-CAM6 and its family models: SON2) or combined as a parcel interacting with radiation (SON1). This study uses derived 2C-ICE frozen hydrometeors water path (IWP) and vertical profile of ice water content (IWC) estimates from CloudSat-CALIPSO satellite data to evaluate IWP/IWC simulations by CMIP6 models in terms of stratiform floating cloud (CIWP/CIWC), stratiform precipitating (Snow: SWP/SWC) and total IWP/IWC (TIWP/TIWC), which is the sum of CIWP/CIWC and SWP/SWC. The spatial map distributions of CIWP/SWP/TIWP, vertical zonally-average and regionally-averaged profiles of the subsets for NOS, SON1, and SON2 in CMIP6 are evaluated. The NOS models show better than SON2 agreements in comparison with CIWP, except for overestimated magnitudes over trade-wind regions over southern ocean. The SON2 models ...
