External project partners
In addition to the core areas of the FESSTVaL campaign, which originate from the thematic areas of the HErZ, some external participants enrich the experiment. They complement us with special measuring strategies, devices and scientific questions.
 | Multiple quadrotor UAVs DLR is developing a swarm of small UAV within the project SWUF-3D for distributed measurements of wind, temperature and humidity. The FESSTVaL infrastructure is a great framework for validation and comparison of the swarm measurements to stationary in-situ and remote sensing data. The swarm measurements support the scientific goals of the project to understand submesoscale structures like for example gusts. (N. Wildmann & T. Wetz) |
 | LiDAR (E. O'Connor) |
 | LiDAR The KIT tests various triple Doppler lidar configurations and develops quality control tests for the improvement and validation of ground-based remote sensing methods for long-term wind measurements. For validation, the lidar measurements with the instruments of the 99 m high measuring tower in Falkenberg are compared with the other lidar systems of the DLR and DWD and the UAVs of the Universität Tübingen (M. Mauder, K. Wolz) |
 | ASSIST-II (D. Turner) |
 | LiDAR (F. Meier) |
 | soil measurements The aim is to quantify the complex coupling between soil and external boundary conditions influencing the dynamics of processes occurring near the Earth's surface. (N. Shokri, H. Nevermann) |
 | Unmanned aerial vehicles The University of Tübingen uses small unmanned research aircraft to record spatially and temporally high-resolution turbulence data and atmospheric boundary layer (ABL) characteristics in order to evaluate and assess lidar systems and the high-resolution numerical model ICON. (J. Bange, A. Platis, J. Boventer) |
 | Solar radiation The aim is to observe the spatial structure of shadows and peaks in irradiance due to clouds by measuring solar irradiance in a spatial grid. This work is part of the Shedding Light On Cloud Shadows-project (chiel.ghost.io/slocs), in which more of the 3D interactions between clouds and radiation and the impact on the surface irradiance should be understood. The contribution to FESSTVaL is by providing more insight in the impact of cold pools on the observed surface irradiance. (C. van Heerwarden, W. Mol) |
