Long-term experiment VERTURM (vertical turbulence measurements). Comparison of measurements and modeling of the vertical distribution of optical turbulence Cn2 in the surface layer

Operation and design of electro-optical systems are affected by atmospheric turbulence, quantified by refractive structure function parameter Cn2. The long-term VerTurM experiment at a rural site in Northwestern Germany served to collect an extended dataset of vertical profiles of Cn2 values up to 64 meters, completed by a characterization of the surface layer meteorology. A micrometeorological model in terms of the Monin-Obukhov similarity theory (MOST) was developed to predict the values of Cn2 and its results were compared to the measurements.
