From the History of Boundary Layer Studies in IFA
Some results of experimental investigations carried out in the IFA concerning the role of turbulence in exchange processes in the boundary layer of the atmosphere are described. From the very beginning, the theory of this field thanks to the works of A.M. Obukhov was far ahead of the experiment, and to verify the predictions of the theory and move forward, it was necessary to create new instruments and techniques. The author, being a student of A.M. Obukhov, personally participated in the creation and practical application of many instruments and techniques. In the present historical review, ten important results are listed, in which the author took direct part, and the first five of them are considered in detail.
