Flooding in Western Europe: what happened in July 2021?
  • EGU news
  • 29 July 2021

From the 13th to the 15th July 2021, a period of intense rainfall led to catastrophic and deadly flooding in Western Europe. Several of EGU’s Division Presidents from natural hazards, hydrology, geomorphology and more, explain what happened and why interdisciplinary disasters like this are difficult to manage.

Impact Factors have increased for all EGU journals in 2020!
  • EGU news
  • 1 July 2021

Newly announced journal metrics for EGU’s journals, managed by our publishing partner Copernicus, have revealed an increase in Impact Factor for all EGU Journals. Several journals, including Atmospheric Chemistry and Physics (ACP), Earth System Dynamics (ESD), Natural Hazards and Earth System Sciences (NHESS) and The Cryosphere (TC) have reached their highest value ever. See the full list of new details on Copernicus’ website.

Physical characteristics of frozen hydrometeors inferred with parameter estimation

Satellite observations sensitive to cloud and precipitation help improve the quality of weather forecasts. However, they are sensitive to things that models do not forecast, such as the shapes and sizes of snow and ice particles. These details can be estimated from the observations themselves and then incorporated in the satellite simulators used in weather forecasting. This approach, known as parameter estimation, will be increasingly useful to build models of poorly known physical processes.

Influence of the representation of convection on the mid-Holocene West African Monsoon

This paper investigates the impact of explicitly resolving convection on the mid-Holocene West African Monsoon rain belt by employing the ICON climate model in high resolution. While the spatial distribution and intensity of the precipitation are improved by this technique, the monsoon extents further north and the mean summer rainfall is higher in the simulation with parameterized convection.

Iodide CIMS and m∕z 62: the detection of HNO3 as NO3− in the presence of PAN, peroxyacetic acid and ozone

We demonstrate in laboratory experiments that the formation of IOx anions (formed in reactions of I− with O3) or acetate anions (formed e.g. by the reaction of I− with peracetic acid) results in unexpected sensitivity of an iodide chemical ionisation mass spectrometer (I-CIMS) to HNO3 at a mass-to-charge ratio of 62. This helps explain observations of apparent high daytime levels of N2O5. Airborne measurements using I-CIMS confirm these conclusions.

GeoTalk: Meet Mengze Li, atmospheric chemist and the Atmospheric Sciences Division’s Early Career Scientist Representative

Hi Mengze, thank you for spending your time with us today. Could you tell our readers a little about yourself? Hi Simon, thanks for the interview today. I’m happy to tell more about myself. I was born in China, lived and studied there until I finished my Bachelor’s study. After that I went to Germany for Master’s and doctoral degrees. Last year I have finished my PhD at Max Planck Institute for Chemistry and stayed there as a postdoctoral researcher …

Will the Arctic be ice free earlier than previously thought?

There is no doubt that the Arctic is currently losing its sea ice as our climate is warming. And this process will carry on as temperatures continue climbing. But the rate at which sea ice will melt in the future and the exact date when the Arctic will be free of sea ice is not known due to several factors (which will be briefly discussed in this post). Torben Koenigk and I have selected climate models that are closest to …

The Sassy Scientist – Postdoc Purgatory

Postdoc appointments: the forgotten terrace of Purgatory. Where researchers are sentenced to linger till either a positions opens in the Heaven of permanent contracts, or they realise that, after all, they are not interested anymore. This terrace is composed of different levels of various length. Nobody knows how many levels there are and how long they are, or should be. Raul asks: What is the ideal length of a postdoc contract? Dear Raul, Let’s get it right out there: the …
