2016-2020年海南西沙海洋环境国家野外科学观测研究站海气通量数据集

海气通量是表征海洋和大气之间物质和能量交换的重要指标，对于理解海洋和大气中不同时空尺度的现象及相互作用关系具有重要意义。本数据集收集和整理了海南西沙海洋环境国家野外科学观测研究站综合气象观测塔 2016–2020 年的海气通量观测数据，提供基于梯度气象子系统观测的6h间隔的水文气象观测数据，以及基于涡动通量观测子系统观测的30min间隔的湍流通量观测数据，经过质量控制后的数据记录达109908条。本数据集共 2 个 txt 文件，分别为基于涡动通量观测子系统获取的 2016 年涡动通量数据（二氧化碳通量、潜热通量、感热通量和动量通量）和基于梯度气象观测子系统获取的2016–2020 年梯度气象数据（风速、风向、气温、相对湿度、气压、降水、海表温度、向下短波辐射、向上短波辐射、向下长波辐射、向上长波辐射和净辐射）。本数据集可以为海气通量参数化方案改进和数据产品研制、区域海气相互作用和气候变化以及深海海洋环境监测和灾害预警等提供重要的基础数据支撑。

Air-sea flux is a crucial indicator characterizing the mass and energy exchange between the ocean and the atmosphere, and it holds great significance for understanding phenomena across various spatio-temporal scales in the ocean and atmosphere as well as their interactive relationships. This dataset collects and organizes air-sea flux observation data from 2016 to 2020 obtained by the integrated meteorological observation tower of the Hainan Xisha Marine Environment National Field Scientific Observation and Research Station. It provides hydro-meteorological observation data at 6-hour intervals measured by the gradient meteorological observation subsystem, as well as turbulent flux observation data at 30-minute intervals collected by the eddy flux observation subsystem. After quality control, the total number of valid data records reaches 109,908. This dataset contains two TXT files, specifically including the 2016 eddy flux data (carbon dioxide flux, latent heat flux, sensible heat flux and momentum flux) acquired by the eddy flux observation subsystem, and the 2016–2020 gradient meteorological data (wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, precipitation, sea surface temperature, downward shortwave radiation, upward shortwave radiation, downward longwave radiation, upward longwave radiation and net radiation) obtained by the gradient meteorological observation subsystem. This dataset can provide important basic data support for the improvement of air-sea flux parameterization schemes, the development of data products, regional air-sea interaction and climate change research, as well as deep-sea marine environmental monitoring and disaster early warning, among other relevant research and application fields.
