High-frequency, hourly, and daily UV measurements from Lake Hoare Meteorological Station (HOEM), McMurdo Dry Valleys, Antarctica (2015-2022, ongoing)

As part of the McMurdo Dry Valleys Long-Term Ecological Research program, total ultraviolet (UV) irradiance has been measured since 2015 using an independent UV radiometer system co-located with the Lake Hoare Meteorological Station (HOEM) in Taylor Valley, McMurdo Dry Valleys, Antarctica. Data are provided at high frequency (5-minute intervals), along with hourly and daily summaries. Users should note that summary statistics may be affected by periods of missing data. Since there is no universally accepted standard for handling gaps in time-series data, users are encouraged to work with the high-frequency data and establish their own criteria for acceptable data completeness to minimize any potential bias.

作为麦克默多干谷长期生态研究计划（McMurdo Dry Valleys Long-Term Ecological Research program）的一部分，自2015年起，研究人员便依托一套独立紫外辐射计系统，在南极洲麦克默多干谷泰勒谷的霍尔湖气象站（Lake Hoare Meteorological Station，缩写HOEM）同址部署，开展总紫外（UV）辐照度监测工作。本数据集提供5分钟间隔的高频观测数据，同时附带逐小时与逐日汇总统计结果。使用者需注意，汇总统计结果可能会受到数据缺失时段的影响。由于目前学界尚未就时序数据缺失值的处理形成通用标准，因此建议使用者优先使用高频观测数据，并自行设定可接受的数据完整度标准，以尽可能降低潜在的统计偏差。
