The Deutscher Wetterdienst's Meteorologisches Observatorium Lindenberg has been designated GRUAN Lead Center and is the first GRUAN network station. Here an inflated balloon for a 1200 UTC radiosonde observation is in the balloon shed, where participants at the GRUAN implementation workshop gathered in February 2008. In addition to upper-air soundings, the observatory also makes most of the GRUAN first and second priority observations.
