| description | This study investigates the relationship of cloud properties and radiative effects with air mass origin during the winter (November–February, 2016–2020) at Ny-Ålesund, Svalbard, through a combination of cloud radar, ceilometer, and microwave radiometer measurements. The liquid cloud fraction (CF) was less than 2%, whereas the ice CF predominantly exceeded 10% below 6 km. The liquid water content (LWC) of mixed-phase clouds (LWC<sub>mix</sub>), which predominantly exist in the boundary layer (CF<sub>mix</sub>: 10–30%), was approximately four times higher than that of liquid clouds (LWC<sub>liq</sub>). Warm air mass advection (<i>warm<sub>adv</sub></i>) cases were closely linked with strong southerly/southwesterly winds, whereas northerly winds brought cold and dry air masses (<i>cold<sub>adv</sub></i>) to the study area. Elevated values of LWC and ice water content (IWC) during <i>warm<sub>adv</sub></i> cases can be explained by the presence of mixed-phase clouds in the boundary layer and ice clouds in the middle troposphere. Consistently, the <i>r<sub>e</sub></i> of ice particles in <i>warm<sub>adv</sub></i> cases was approximately 5–10 μm larger than that in <i>cold<sub>adv</sub></i> cases at all altitudes. A high CF and cloud water content in <i>warm<sub>adv</sub></i> cases contributed to a 33% (69 W m<sup>−2</sup>) increase in downward longwave (LW) fluxes compared to cloud-free conditions. |
