“The Onsala Twin Telescopes are part of the global geodetic Very Long Baseline Interferometry (VLBI) network. Radio telescopes all around the globe are observing extra-galactic radio sources simultaneously to determine Earth orientation parameters, source positions and station coordinates, as well as velocities. Geodetic Very Long Baseline Interferometry is used to maintain the International ...[Read More]

The Zugspitze Geodynamic Observatory Germany (ZUGOG) has been setup on the summit of mountain Zugspitze at an altitude of almost 3000 m during 2018 with the main scientific objective being a better understanding of seasonal and long-term mass redistributions in the European Alps. This knowledge is very important (e.g. with regard to water storage and its high sensitivity to climate change), but is ...[Read More]

The color and symmetry of the Amazon Tall Tower Observatory (ATTO) sticks out against the endless green of the rainforest. Built in a remote and pristine location, the ATTO tower is the tallest construction in South America. In a joint Brazilian-German project, atmospheric scientists aim to unravel the interaction of pristine rainforest with the atmosphere. With its height of 325 meters, the ATTO ...[Read More]
