Imaggeo On Monday: Catching a glimpse of the Mesosphere
In the midst of summer when the sun does not set at high latitudes one can sometimes catch a glimpse of the mesosphere shortly after sunset or before sunrise. These thin veils, known as noctilucent clouds, are the highest known cloud-like structures forming at about 80km above the surface. At this height, they are still …[Read More]
Imaggeo On Monday: “Smoking” peaks of the Patagonian batholith
The indigenous name of the 3405 meter high Fitz Roy mountain in Patagonia, on the border between Argentina and Chile, is frequently translated as “smoking mountain”. This photo may visually explain an origin of this name. On the day the photo was taken, vortices downwind of the peak drew warmer, humid air from below, forming …[Read More]
GeoPolicy: EGU science for policy: what’s coming up in 2021?
There were a lot of big changes to the EGU’s science for policy programme in 2020 with many of our activities, such as the annual science for policy event and science-policy pairing scheme, moving online. But 2021 promises to be an even bigger year with a greater number of opportunities to engage and activities becoming …[Read More]
Imaggeo On Monday: The sudden stratospheric warming on February 12, 2018
The image captures an atmospheric extreme event, a so-called sudden stratospheric warming (SSW) that occurred on Feb. 12, 2018. It is visualized through potential vorticity above the North Pole at the 10hPa level (~30km) above the Earth’s surface and consists of a split of the winter polar vortex into two separate vortices that interact with …[Read More]
Imaggeo On Monday: Revealing the secrets of the Arctic sky
When it is dark over Ny Ålesund, Svalbard, a bright green laser beam can be seen quite often, shooting from the AWIPEV Arctic Research Base observatory towards the sky. This beam belongs to “KARLi” the Koldewey Aerosol Raman Lidar, run by the Alfred Wegener Institute for more than 25 years, which contributes to long-term, atmospheric …[Read More]

Imaggeo On Monday: Konsfjorden and Kronebreen glacier
Taken shortly after our departure from Ny-Ålesund after our first “Lost Meteorites” field trial in Greenland testing new equipment that can be used to discover ‘missing’ iron meteorites in Antarctica, the return flight gave incredible views of the surrounding landscape. This photo was taken looking down to the icy waters of Kongsfjorden on the west …[Read More]
Imaggeo On Monday: Nature of ice crystals
Moisture coming from the ground is freezing at the entrances of small ground pockets, shaping wonderful natural ice crystals, during a very cold and dry winter in Poland in 2019. Description by Katarzyna Walczak, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (and others) can submit their photographs …[Read More]
