Sonic Anemometer Comparison and Measurements in the Atmospheric Surface Layer

[摘要] Results of comparison measurements of a sonic anemometer developed at Kyoto University and one developed at the University of Washington are presented. Good agreement between the instruments has been obtained.Several techniques of data reduction have been applied. Comparison between the digital and analogue techniques gave consistent results.Besides comparison measurements, general observations of atmospheric turbulence are presented including variance spectra of the vertical wind component w and temperature T for various stabilities, and cospectra as well as coherence between w and T.
