Spatial distribution of atmospheric refractive index structure parameter about the dome

Microtemperature method is used to measure the turbulence strength of different positions near the telescopic dome which is an isolated building. From analyzing the refractive index structure parameter near the dome and the same parameter at tower, the parameter of turbulence at altitude of 8.2 m, 8.5 m, 9.0 m are stronger than that of same altitude of general atmosphere. The refractive index structure parameters of equidistance between sensors and dome in different directions are different. The vertical turbulence intensity is stronger than the horizontal turbulence intensity. It is unreliable to consider the range near dome as near ground. The spectrum of temperature fluctuations near the dome follows the －5/3 law．
