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.

本数据集收录北极地表热预算（Surface Heat Budget of the Arctic, SHEBA）地表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影响方式。本数据集集合包含北极多个观测站点的垂直分辨云微物理特性数据，所有观测均基于各站点现有的地表遥感传感器测量结果。研究团队采用多种云微物理反演算法，先识别云的类型（相态），再分别表征液态与冰态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维持统一的反演流程，但各台站均配备独特的云观测仪器，这会为反演结果带来独有的站点特异性特征。
