. The French–German Arctic research base AWIPEV (the Alfred Wegener InstituteHelmholtz Centre for Polar and Marine Research – AWI – and the French PolarInstitute Paul Emile Victor – PEV) at Ny-Alesund, Svalbard, is a uniquestation for monitoring cloud-related processes in the Arctic. For the firsttime, data from a set of ground-based instruments at the AWIPEV observatory areanalyzed to characterize the vertical structure of clouds. For this study, a14-month dataset from Cloudnet combining observations from a ceilometer, a94 GHz cloud radar, and a microwave radiometer is used. A total cloudoccurrence of ∼81  %, with 44.8 % multilayer and 36 %single-layer clouds, was found. Among single-layer clouds the occurrence ofliquid, ice, and mixed-phase clouds was 6.4 %, 9 %, and 20.6 %,respectively. It was found that more than 90 % of single-layer liquid andmixed-phase clouds have liquid water path (LWP) values lower than 100 and200 g m −2 , respectively. Mean values of ice water path (IWP) for iceand mixed-phase clouds were found to be 273 and 164 g m −2 ,respectively. The different types of single-layer clouds are also related toin-cloud temperature and the relative humidity under which they occur. Statisticsbased on observations are compared to ICOsahedral Non-hydrostatic (ICON)model output. Distinct differences in liquid-phase occurrence in observationsand the model at different environmental temperatures lead to higheroccurrence of pure ice clouds. A lower occurrence of mixed-phase clouds inthe model at temperatures between −20  and −5 ∘ C becomes evident.The analyzed dataset is useful for satellite validation and model evaluation.
