Update: Campaign postponed
May 7 2020:
Unfortunately, due to the COVID-19 pandemic, the FESSTVaL measurement experiment cannot take place in summer 2020 as planned.It will be postponed to the coming year and supported by preparatory measurements "at home".More information on this on the corresponding webpages in the menu above FESST@home 2020.
FESSTVaL (Field Experiment on submesoscale spatio-temporal variability in Lindenberg) is a measurement campaign initiated by the Hans-Ertel-Center for Weather Research (HErZ).
It will take place in the summer months of the year 2020 at the Meteorological Observatory Lindenberg - Richard-Aßmann-Observatorium (MOL-RAO) of the German Weatherservice (DWD) near Berlin. To identify the sources of sub-mesoscale variability, the measurement campaign focuses on three main aspects: atmospheric boundary layer structures, cold pools, and gusts of wind.
In order to capture phenomena at the submesoscale (500 m – 5 km), a hierarchical measurement strategy will be realized. This includes wind profiling stations with a coordinated scanning strategy of several Doppler Lidars, two mobile profiler to measure thermodynamic properties of the atmosphere and precipitation, more than 100 stations with near-surface measurements of air temperature and pressure, more than 20 automatic weather stations, an X-Band radar, and a number of energy balance stations. This equipment is supplemented by the extensive ground-based remote sensing array at the MOL-RAO. Complementing to this, the added value of a citizen-science measurement network is investigated during the campaign with “Internet-of-things” based technology and low-cost sensors build and maintained by citizens. The FESSTVaL measurements will be complemented by high-resolution large-eddy simulations (ICON-LES) comprising the site.
