This paper desicribes a wind tunnel experimental results of concentrarion fluctuation of tracer gas emitted from an elevated point source located upstream position of a finite width wall in a simulated atmospheric boundary layer. The concentration fluctuation was measured with a fast response concentration detecter. The obtained experimental results of mean concentration, time series of concentraion fluctuations, and the probability density functions of concentration fluctuation were compared with those of a flat plate condition. Tracer gas emitted from upstream position of the wall was earlier detected in the surface than on a flat plate condition by entraining into the cavity region. And below the wall fluctuatons of concentration were considerably smoother.
