Barrow buoy data - Emaiksoun Lake, 2012 (CALON)

This dataset is comprised of instrumented buoy data collected on Emaiksoun Lake in Barrow, Alaska for the purposes of quantifying the over-lake meteorology and surface energy balance. Hourly mean weather, wave height, water temperature, and energy balance data were collected from a TIDAS-900 data buoy deployed near the center of the lake over a 4-year period (2012-2015). Primary responsible individuals include John Lenters and Brittany Potter, assisted at times by other CALON collaborators. The 2012 dataset provides information for the summer of 2012 (i.e., the majority of the ice-free season). All variables represent hourly means, with units provided below each variable name. The data buoy was equipped with duplicate Vaisala WXT520 weather sensors (labeled E and W) and duplicate Kipp & Zonen CNR4 net radiometers (labeled N and S), each facing in opposite cardinal directions. The labeling is only meant to indicate relative orientation on the buoy mast, as the buoy itself was able to rotate with the wind direction. Additional sensors included an RBR temperature string (nodes at 8 depths; 25-cm intervals down to 2.25 m), a LI-COR PAR sensor, and a 3-axis accelerometer (to measure wave height). The data have not undergone extensive QA/QC, and missing data are labeled as "NAN."本数据集由采集于美国阿拉斯加州巴罗（Barrow）埃迈克松湖（Emaiksoun Lake）的仪器浮标观测数据组成，旨在量化湖面气象特征与地表能量平衡。2012年至2015年的4年观测周期内，部署于湖中心附近的TIDAS-900型数据浮标（TIDAS-900 data buoy）采集了逐小时平均气象、浪高、水温及能量平衡数据。本数据集的主要负责人为约翰·伦特斯（John Lenters）与布里塔尼·波特（Brittany Potter），期间曾得到CALON协作团队成员的协助。2012年数据集涵盖了2012年夏季（即该年度绝大多数无冰期）的相关观测数据。所有变量均为逐小时平均值，各变量的单位标注于其名称下方。该数据浮标搭载了两套分别标记为E和W的维萨拉WXT520型气象传感器（Vaisala WXT520 weather sensors），以及两套分别标记为N和S的Kipp & Zonen CNR4型净辐射计（Kipp & Zonen CNR4 net radiometers），二者均朝向相反的主方位。浮标上的传感器标记仅用于指示其在桅杆上的相对朝向，因浮标本身可随风向旋转。额外搭载的传感器包括RBR型温度剖面仪（设置有8个深度节点，以25厘米为间隔直至2.25米水深）、LI-COR型光合有效辐射（Photosynthetically Active Radiation，简称PAR）传感器，以及用于测量浪高的三轴加速度计。本数据集未经过全面的质量保证与质量控制（QA/QC），缺失数据以“NAN”标记。
