The EGU Election Autumn 2019 for the next EGU President, General Secretary, and Division Presidents will take place from 1 to 30 November 2019. You are kindly asked to propose a candidate to any of these vacancies by 15 September 2019. You are welcome and encouraged to nominate yourself.
EGU’s Committee on Education aims to provide support for higher education, from organising workshops to providing networking opportunities for all those teaching geoscience in higher education. We invite PhD students, postgraduates, research fellows, academic staff and any others teaching geoscience in higher education to fill in a short survey to help us understand the role EGU could play in further supporting higher education.
The June 2019 edition of the EGU email newsletter, the monthly information service for Union members, is now available.
The call for session proposals for the EGU General Assembly 2020 is now open. Until 5 September you can suggest new scientific sessions with conveners and description, and/or submit short course ideas. The deadline to submit proposals for Union Symposia and Great Debates is 15 August. The next EGU General Assembly is taking place in Vienna, Austria on 3–8 May 2020.
EGU is committed to standing up for international cooperation in science and taking a leading role within the scientific community in order to reduce barriers to scientific collaboration and cooperation across Europe, let alone increase them, as these would be a tremendous loss to European nations, to the international scientific community and to humanity as a whole.
The quantification of anthropogenic emissions with current CO2 satellite sensors is difficult, but NO2 is co-emitted, making it a suitable tracer of recently emitted CO2. We analyze enhancements of CO2 and NO2 observed by OCO-2 and S5P and estimate the CO2plume cross-sectional fluxes that we compare with emission databases. Our results demonstrate the usefulness of simultaneous satellite observations of CO2 and NO2 as envisaged for the European Copernicus anthropogenic CO2 monitoring mission
We describe a technique used to locate and classify critical points in 2-D flow fields at the solar photosphere obtained from the evolution of the line-of-sight magnetic field in a region close to the magnetic polarity inversion line of a fully emerged active region. We apply this technique to locate a particular kind of critical point associated to vortex flows, which are considered important, since they can twist and interweave the foot points of flux tubes and generate magnetic reconnection.
The 18th and early 19th centuries saw pronounced climatic variations with impacts on the environment and society. Although instrumental meteorological data for that period exist, only a small fraction has been the subject of research. This study provides an overview of early instrumental meteorological records in Switzerland resulting from an archive survey and demonstrates the great potential of such data. It is accompanied by the online publication of the imaged data series and metadata.
The Glacier Area Mapping for Discharge from the Asian Mountains (GAMDAM) glacier inventory was updated to revise the underestimated glacier area in the first version. The total number and area of glaciers are 134 770 and 100 693 ± 11 790 km2 from 453 Landsat images, which were carefully selected for the period from 1990 to 2010, to avoid mountain shadow, cloud cover, and seasonal snow cover.
Dr Assaf Sukenik is Senior Scientist at Kinneret Limnological Laboratory of the Israel Oceanographic and Limnological Research. His research interests concern the physiology and biochemistry of freshwater and marine algae, Cyanobacteria and algal toxins, the water quality of freshwater ecosystems. What are cyanobacteria and what is their natural habitat? Cyanobacteria (from the Greek word κυανοσ =blue), also known as blue-green algae, constitute the largest, most diverse, and most widely distributed group of photosynthetic oxygenic (oxygen-evolving) prokaryotes1. They acquire their energy …
Do you enjoy the EGU’s annual General Assembly but wish you could play a more active role in shaping the programme? This year, why not propose a Union Symposia or Great Debate? Each year at the General Assembly, the conference features a limited number of Union Symposia (US) and Great Debates (GDB), which can be proposed by anyone in the scientific community. These high-profile, union-wide events are intended to be cutting-edge, current, and of interest to a broad range of …
The increase in air and water temperature due to climate change drives the retreat in the Arctic sea-ice cover. During summer, when sunlight reaches the Arctic, the absorption of heat by the dark ocean water enhances the sea-ice melt through the ice-albedo feedback. During winter, when sunlight does not reach the Arctic, another feedback is at work, as storms enhance the energy transfer between air, ice and water… How can storms enhance sea-ice melting? In summer, when the Arctic sea-ice …
