Cloud microphysical properties at Arctic atmospheric observatories: Barrow, Alaska

This data set contains cloud microphysical properties data for Barrow, Alaska. 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.

本数据集包含美国阿拉斯加州巴罗（Barrow）地区的云微物理特性（cloud microphysical properties）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机制。本数据集集合收录了北极多站点的垂直分辨云微物理特性数据，其观测数据源自各站点现有可用的地基遥感传感器（surface-based remote-sensors）测量结果。研究团队采用多种云微物理反演算法（cloud microphysics retrieval algorithms），首先识别云的类型与相态（phase），随后表征液态与冰相下水凝物（hydrometeor）的特征尺度及含水量。尽管已尝试在不同观测台站间保持统一的反演流程，但每个台站均配备专属的云观测仪器，这会为反演结果带来独特的站点特异性特征。
