研究大气湍流及其在近地面层内输送动量、热量、水蒸气和其他成分的作用一直是微气象学的中心目标。这项研究的关键是关于所有有关参数波动的详细资料。感兴趣的频率覆盖了近五十年的范围，对应的运动尺度从几厘米到几公里，对实验者提出了严峻的挑战。在过去的50年里，已经尝试了许多不同的测量技术，并取得了不同程度的成功。特别注意速度场的波动，因为它们对大气中的湍流输送很重要。
The study of atmospheric turbulence and its role in transporting momentum, heat, water vapor and other constituents within the layers close to the ground has been a central goal in micrometeorology. Essential to such a study is detailed information on the fluctuations of all relevant parameters. The frequencies of interest cover a range of nearly five decades, corresponding to scales of motion ranging from a few centimeters to several kilometers, presenting a serious challenge to the experimentalist. Over the last 50 years a number of different measurement techniques have been tried with varying degrees of success. Particular attention was given to fluctuations in the velocity field because of their importance to turbulent transport in the atmosphere.
