摘要：

The optical trubulence on the coast has been measured with balloon borne thermosonde developed by ourselves. The thermosonde is lifted up to 20 km by hydrogen inflated balloons at a climbing rate of 4 m&middots-1. The microthermal sensor is coupled to a meteorologic radiosonde (59 type), which is able to transmit pressure, temperature, humidity, and refractive index structure constant each 30 m height interval. The outer scale is estimated by Tatarski formula. Comparing with AFGL AMOS model, Hufnagel model, Xinglong fitting model based on balloon measurements from Xinglong station, Beijing observatory, it is shown that refractive index structure constant measured over sea is 2 orders of magnitude higher than those of the models. Profile of refractive index structure constant falls off slowly from the surfaces relatively strong optical turbulence with nearly the same lapsing rate. There is no strong turbulence region at the tropopause, the outer scale value is less than 30 m and a formula of outer scale profile has been fitted.
