Experimental study of obtaining atmospheric coherent length from turbulence profile
2004
In this paper, two methods were used to get the atmospheric coherent length of slope way in the atmospheric boundary layer. A set of microthermal sensor was installed on a 32 meters high tower, it was used to get the turbulence profile together with a Doppler sodar. The atmospheric coherent length could be gained from the integral of turbulence profile. A small bulb was hoisted with a kite balloon, a difference optical system was used to measure the atmospheric coherent length from fluctuation of arrival angle.The results of both these two methods could show the character of temporal variation. The correlation of the results was quite well. At last, some problems of getting atmospheric coherent length from the integral of turbulence profile were discussed.
