The META-WT project was designed to perform a 4-weeks seismic experiment in Germany with a dense seismic array of ~400 three-component geophones that covered (1) a 2.5km x 2.5km wind farm area in Brandenburg, Germany, with almost 200 wind turbines (WTs) and a well-studied subsurface structure and (2) a 20-km long radial line from the center of the wind farm with one geophone every half-kilometer. The objective was to capture the spatio-temporal seismic wave-field signature of the wind farm from continuous recordings of ambient noise. Due to the dense interstation distance and proposed geometry the experiment allowed for analyzing both small-scale wave field characteristics at an unprecedented spatial resolution and the longer distance radiation pattern of the wind farm. Waveform data is available from the GEOFON data centre, under network code XF.
