Long-term experiment VERTURM(vertical turbulence measurements): comparison of measurements and modeling of the vertical distribution optical turbulence C_n~2 in the surface layer

摘要

Operation and design of electro-optical systems are affected by atmospheric turbulence, quantified by refractive structure function parameter C_n~2. The long-term VerTurM experiment at a rural site in Northwestern Germany served to collect an extended dataset of vertical profiles of C_n~2 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 C_n~2 and its results were compared to the measurements.
