Abstract

The distribution of optical turbulence with height over the plateau is one of the most important points for laser propagation in the atmosphere. The simultaneous measurement of optical turbulence at three layers (2m, 5m and 10m) was carried out on Plateau with sand-grass underlying surface. The measured refraction index structure constant at 2m and local sunrise and sunset times were used to verify the applicability of the HAP model. The index of the HAP model and its diurnal variation are re-fitted by the measured refraction index structure constant. Compared with the traditional model, the average correlation coefficient and root mean square error are increased from 0.893, 0.796, 0.263 and 0.286 to 0.899, 0.816, 0.158 and 0.243, respectively. It is improved that the applicability of the new HAP model to plateau atmosphere. The new HAP model provides a new reference for the evaluation of the turbulence effect for plateau laser atmospheric transmission.
