Abstract

The refractive index structure parameter C²_n is a physical quantity used to characterize atmospheric optical turbulence, which is of great significance to the study of light wave transmission in turbulent atmosphere. In this paper, the C²_n of coastal area from November 2019 to early January 2020 were measured by shipborne ultrasonic anemometers and microthermometer. Turbulence characteristics are statistically analyzed and the differences between results derived from the two measurement methods are discussed. The results show that the C²_n measured by two instruments is generally consistent but have deviation. It is preliminarily inferred that the ultrasonic anemometer will oscillate due to the influence of the experimental environment on the wind field and the land-sea breeze, resulting high frequency noise that leads to higher measurement results than the micro-thermometer.
