Cloud microphysical properties at Arctic atmospheric observatories: SHEBA

This data set contains cloud microphysical properties data for the Surface Heat Budget of the Arctic (SHEBA) surface-based sites. Cloud microphysical properties determine the manner in which clouds impact atmospheric radiation and the hydrological cycle. This collection of data sets documents vertically-resolved cloud microphysical properties at multiple locations across the Arctic. Observations are based on the available surface-based, remote-sensors measurements at each site. A variety of cloud microphysics retrieval algorithms are employed to first identify the cloud type (phase) and then characterize the hydrometeor characteristic size and water content for both liquid and ice phases. While an attempt has been made to maintain consistent retrievals across the different observatories, each has a unique set of cloud observation instruments which can impose unique, site-specific signatures on the retrieval results.

本数据集包含北极地表热收支（Surface Heat Budget of the Arctic, SHEBA）地面观测站点的云微物理特性数据。云微物理特性决定了云对大气辐射与水文循环的作用机制。该数据集记录了北极多个站点的垂直分辨率云微物理特性观测结果，其观测数据源于各站点现有的地面遥感传感器测量值。研究采用多种云微物理反演算法，首先识别云的类型（相态），随后分别表征液相与冰相水成物的特征尺度及含水量。尽管已尽力在不同观测台站间保持反演结果的一致性，但每个台站均配备了专属的云观测仪器，这会为反演结果带来独有的站点特异性特征。
