Estimation of atmospheric optical turbulence profiles in different environments based on Tatarski parameterization scheme

Atmospheric optical turbulence severely restricts the performance of optical systems. In order to reduce the influence of atmospheric turbulence and meet the application of photoelectric engineering, it is very important to accurately estimate the atmospheric optical turbulence profiles in different scenes. Based on the Tatarski optical turbulence parameterization scheme and the representative outer scale models, the meteorological data measured by the sounding instrument were used to estimate optical turbulence profiles of inland area(Hefei), sea-land interface (Maoming) and open sea, respectively. The estimations were compared with the observed profiles at Hefei and Maoming. There is a good consistency both in trend and magnitude, which provides the evidence for estimating the atmospheric optical turbulence profile of open sea with this model. The results show that the model can precisely estimate the optical turbulence profiles in different environments. In addition, it is found that the occurrence of upper air optical turbulence is closely related to wind shear and temperature gradient.
