The light’s interaction with matter enables scientists to observe greenhouse gases from space, but also creates the shifting blue tones throughout the mountains that hikers travel long distances to admire! The blue shades are created by an effect called Raleigh scattering, where very small atmospheric particles between the viewer (or camera) and the mountains cause the shorter wavelength lig ...[Read More]

Imaggeo On Monday: Blood moon over Germany
A blood moon occurs during a total lunar eclipse. The sunlight falling through the air layers of the Earth’s atmosphere is refracted inwards, whereby especially the short-wave blue components are weakened by scattering. The long-wave red components, on the other hand, still reach the moon, which leads to the red colouring. Photo by Simon Fuhrmann shared on imaggeo.egu.eu. Imagg ...[Read More]

GeoPolicy: What’s coming up for 2023?
2022 was an exciting GeoPolicy year with many new science for policy projects and opportunities beginning and others being restored after a 2020/2021 pause due to COVID19. In 2023, we hope to build on EGU’s current initiatives and bring you yet more opportunities to engage and get involved in European policy! This blog post will kick-off the New Year by outlining a few of the key science for polic ...[Read More]

A touch of space weather! An EGU funded outreach project for blind and visually impaired students
We can all probably agree that the Northern Lights are one of the world’s most spectacular natural displays. But how do we share this beauty with children who are blind? How do we explain the processes behind the aurora creation to the visually impaired when all the illustrations of Earth’s magnetosphere are in 2D? The Northern Lights are just one of the consequences of ‘space weather’. Space weat ...[Read More]

Imaggeo On Monday: Aurora show on the road
In Sweden a beautiful Northern Lights show proceeds unnoticed by the busy drivers passing by. The Northern Lights or Aurora Borealis are spectacular lights created as a result of disturbances in the Earth’s magnetosphere caused by solar winds. They are visible at both polar regions and or often seen as veils or lines of greenish-blue light. Photo by Junbin Zhao shared on imaggeo.egu.eu. &nbs ...[Read More]

EGU’s Life-Work Balance Group shares their New Year’s resolutions
With 2023 just around the corner, we asked EGU’s Life-Work Balance Group members what their New Year’s resolutions are, and we want to share them with you! ‘I live in the Arctic, where we don’t get much sunlight and the brightest part of the day I usually spend in my (windowless) office. I will make a better attempt to go outside for a quick walk, or to get some fresh air during the d ...[Read More]

Imaggeo On Monday: Melt water lake on 79°N Glacier in Greenland
Melt water lakes are an impressive and beautiful consequence of warm summer temperatures on Greenlands glaciers. This photo of such a lake with clear blue water was taken from a helicopter on the 79°N Glacier in northeast Greenland during an expedition in July 2018. Supraglacial melt water runs along the surface slope into depressions where the water is accumulating until it refreezes or drains. P ...[Read More]

GeoTalk: meet Francesco Avanzi, researcher in meltwater security!
Hi Francesco. Thanks for agreeing to this interview! To break the ice, could you tell our readers a bit about yourself and your research? Hey Simon! I’m an Italian hydrologist and earned a PhD at Politecnico di Milano with a dissertation on how snowmelt contributes to seasonal runoff. I then did a postdoc at UC Berkeley, California, where I collaborated with a major US hydropower company to improv ...[Read More]

GeoRoundup: the highlights of EGU Journals published during December!
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For December, the Divisions we are featuring are: Cryosphere (CR), Nonlinear Processes in Geoscience (NP) and Soil System Science (SSS). They are served by the journals: Biogeosciences (BG), Earth Surface Dynamics (ESu ...[Read More]
