  1. 1. Turbulence Intensity During Low-Level Jets in the Baltic Sea

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Thomasson August; [2021]
    Keywords : Low-Level Jet; Turbulence intensity; Shear sheltering; LiDAR; Baltic Sea; Low-Level Jet; Turbulensintesitet; Shear sheltering; LiDAR; Östersjön;

    Abstract : Low-level jets (LLJs) are local wind speed maximums in the atmospheric boundary layer. In the Baltic Sea, LLJs are frequently occurring in spring and summer. It is an important phenomena to consider for wind energy parks, and changes in turbulence during the jets can effect the efficiency of said parks. READ MORE

  2. 2. Atmospheric Attenuation for Lidar Systems in Adverse Weather Conditions

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johan Viklund; [2021]
    Keywords : Lidar; Lidar equation; Extinction coefficient; Signal attenuation;

    Abstract : In this study, the weather impact on lidar signals has been researched. A lidar system was placed with a target at approximately 90 m and has together with a weather station collected data for about a year before this study. READ MORE

  3. 3. Operational data extraction using visual perception

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
