中文说明：涡度协方差（又称涡动相关法）技术是测量和计算大气边界层内垂直湍流通量的重要大气测量技术。该方法分析了高频风和标量大气数据系列，并产生这些属性的通量的值。是用于气象学和其他应用程序（微气象学、海洋学、水文学、农业科学、工业和监管应用等）确定的微量气体交换率对自然生态系统和农业等领域的统计方法，量化的气体排放率从其他土地和水的地区。它经常被用来估计动量，热量，水蒸汽，二氧化碳和甲烷通量。
English Description：
The eddy covariance (also known as eddy correlation and eddy flux) technique is a key atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers. The method analyzes high-frequency wind and scalar atmospheric data series, and yields values of fluxes of these properties. It is a statistical method used in meteorology and other applications (micrometeorology, oceanography, hydrology, agricultural sciences, industrial and regulatory applications, etc.) to determine exchange rates of trace gases over natural ecosystems and agricultural fields, and to quantify gas emissions rates from other land and water areas. It is frequently used to estimate momentum, heat, water vapour, carbon dioxide and methane fluxes. The technique has additionally proven applicable under water to the benthic zone for measuring oxygen fluxes between seafloor and overlying water.[6] In these environments, the technique is generally known
