Long-term Boundary Layer Scintillometer (BLS) turbulence measurements were performed over the Baltic Sea and statistics are presented. The BLS was also used as a transmissometer and its performance was compared to a commercial visibility meter.

Our aim is to characterize the optical turbulence over the urban areas. Since it is difficult to measure 𝐶2/𝑛 (see PDF) continuously over an urban area, we explore the possibility of using a mesoscale weather prediction model to predict 𝐶2/

We report on results of the field trial carried out in the dome of the 2.5 m Isaac Newton Telescope on the island of La Palma (Canary Islands, Spain). The goal of the trial was to characterize optical hrrbulence in the confined space of the observato

Military operations on target practice and wind farms demand on knowledge of the turbulent state and wind speed in the surrounding atmosphere. However, the definition of turbulence is completely different in both cases. In the military context we spe

High frequency fluctuations in the refractive index are the main atmospheric influence on wave propagation in the atmosphere. They are caused mainly from variations in atmospheric temperature. Ultrasonic anemometers have been established as common to
