Dataset of lake ozone flux measurements and auxiliary data

Dataset of O₃ fluxes measured by the eddy covariance system over Lake Kuivajärvi during 23 days period in August and September 2012. The lake is located in the vicinity of the Hyytiälä Forestry Field Station and SMEAR II Station in Southern Finland. The dataset consists of post-processed and quality filtered fluxes and auxiliary measurements that were used in the analysis. The flux measurements were performed on the lake platform, by using an ultrasonic anemometer (Metek USA-1, GmbH, Elmshorn, Germany) to measure the three wind velocity components and sonic temperature and a fast chemiluminescent gas analyzer FOS (Sextant Technology Ltd, New Zealand) that measured O₃ concentration.本数据集为2012年8月至9月期间，于芬兰库伊瓦亚尔维湖（Lake Kuivajärvi）上空通过涡度协方差系统（eddy covariance system）测得的臭氧（O₃）通量数据，观测周期共计23天。该湖坐落于芬兰南部的海蒂亚拉林业野外站（Hyytiälä Forestry Field Station）与SMEAR II观测站周边区域。本数据集包含经后处理与质量过滤的通量数据，以及分析过程中使用的辅助观测数据。通量观测工作在湖面观测平台开展，采用超声风速仪（ultrasonic anemometer，型号为德国埃尔姆斯霍恩Metek GmbH公司生产的USA-1）测量三维风速分量与声速温度，并搭配快速化学发光气体分析仪FOS（fast chemiluminescent gas analyzer FOS，新西兰Sextant Technology有限公司制造）以监测臭氧浓度。
