Konstantinos Kourtidis also added a comment to the image, explaining more about how lenticular clouds like these can form: …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For August, the Divisions we are featuring are: Geodesy (G), Geodynamics (GD) and Earth and Space Science Informatics (ESSI). They are served by the …[Read More]
The solar eclipse of November 3, 2013, as observed from the MSG satellite, in geostationary orbit 36000km above the equator. The eclipsed area, where the shadow of the full Moon reached the Earth’s surface, moved over the Atlantic Ocean and Africa.

“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 Terrestrial Reference …[Read More]
If you are a scientist you probably know the value of a good, well designed image. The right graph or diagram can help the reader to really grasp the meaning of a complicated theory or process, help to illuminate a critical piece of data, or highlight a key finding. But whilst much advice exists about …[Read More]
