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月间，在芬兰南部屈瓦亚尔维湖（Lake Kuivajärvi）上空通过涡度协方差系统（eddy covariance system）观测得到的臭氧（O₃）通量数据，观测周期共计23天。该湖位于芬兰南部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，以及分析过程中所用的辅助测量数据。通量观测依托湖面观测平台开展，采用德国埃尔姆斯霍恩Metek GmbH公司生产的超声波风速仪（Metek USA-1型号）测定三维风速分量与声温，并使用新西兰Sextant Technology Ltd公司生产的快速化学发光式气体分析仪FOS测定臭氧浓度。
