ICOS at vEGU2021

19 April 2021 to 30 April 2021

EGU 2021 - consider submitting abstract to one of the ICOS convened sessions

General Assembly 2021, traditionally held each spring in Vienna, Austria, will take place entirely online due to the continuing risks posed by the coronavirus pandemic and the resulting restrictions on international travel. 

EGU and its conference partner, Copernicus Meetings, have opened the meeting’s call for abstracts. Abstracts will be accepted until 20 January 2021 at 13:00 CET.

Since EGU will be offering a more complete experience in 2021, they will be charging a registration fee, but the cost will be substantially lower than for an in-person annual meeting. Visit the vEGU21 website for more practical information.

ICOS convened sessions are listed below. Click on each session title to learn more about the session theme, the conveners and abstract submission. 

Climate change is causing abrupt changes in greenhouse gas (GHG) cycles, either by altering biogenic fluxes, or changes in anthropogenic emissions as witnessed during the Covid-19 pandemic. Hence, we need to integrate all feedbacks taking place between the climate system and the GHG cycles. While the Covid-19 shutdown led to 17% reduction in daily global CO2 emissions, large forest-fires erupted across the Americas, Australia and the Arctic circle in 2019 and 2020, releasing greenhouse gases and destroyed forests which take up CO2. Global warming leads to early, long summers causing droughts and forests fires. 2018 was one of the driest summers in Europe, resulting in forest carbon sinks decreasing or even turning forests into sources in some cases. Anomalously high solar radiation also led to extreme algal blooms in the Baltic Sea. Thus the feedbacks between the climate system and GHG cycles are multi-dimensional and complex, and need inter-disciplinary research.

For this session, we invite abstracts from observational and modeling studies examining and integrating extreme changes in GHGs (biogenic and/or anthropogenic) and their feedbacks to the climate system. For example (but not limited to):
 1. Aftermath of COVID-19 lockdown, emerging into the new normal.
 2. Effect of forest fires in 2019 and 2020 on regional to global scale.
 3. Warm and wet winter of 2019/2020 and its impact on terrestrial and marine ecosystems.
 4. Dry and hot European summers and subsequent droughts since 2018.

Abstract submission

With the COVID-19 crisis, policy-makers and the public are turning to scientists more than ever, hoping they provide answers and guide decisions. What we as environmental scientists and science communicators can learn from the current situation? How can we better impact the policy-makers so that the responsible decisions are taken?
This session seeks a breadth of contributions discussing how the community of environmental scientists could better bridge the gap between science and decision-making. We would, for example, like to discuss:

  • What kind of communications and engagement strategies work and successfully affect policy-makers?
  • How are science communication and policy engagement practices shifting due to the current COVID-19 crisis and what can environmental science learn from it?
  • We invite both practical cases and theoretical approaches.
  • We are interested in success cases, but we also encourage scientists, organizations, and media representatives to let us learn from less successful experiences and their analyses.

Abstract submission

The UN 2030 Agenda for Sustainable Development is an urgent call for a global partnership for action. The new paradigm of the Paris Agreement puts additional responsibility on scientists to provide data and knowledge to inform climate action for the benefit of society. Together with the other UN conventions (on biological diversity and on disaster risk reduction), these frameworks are highly dependent on evidence-based information derived from geosciences. After having developed crucial capacities on the regional level, Research Infrastructures and other data providers need to upgrade their cooperation efforts and coordinate their actions on the global level. They must ensure a sustainable production of data, products and services in line with the demands of the decision-makers. To deliver on the expectations of the UN system in support of policy-makers, actors from different disciplines (observation, modeling, reporting…) have to intensify their collaborative efforts.
In this session, we welcome abstracts presenting the recent developments in international cooperation efforts, global integration of data sets, initiatives to support climate services and especially the Monitoring, Reporting and Verification mechanism of the Paris Agreement. We also wish to stage the role of disciplines belonging to the human and social fields in achieving the objective.

Abstract submission

The Earth is a highly complex system, formed by a large variety of interacting subsystems, such as the biosphere, atmosphere, hydrosphere, cryosphere, and lithosphere. Our capacity to understand the system depends on our capability to observe, analyze, and model these subsystems and their interactions. A holistic understanding is needed to deal with the rapid global change in, for instance, climate, biodiversity, food production, sustainability, and energy supply. Such holistic understanding is only possible if we study complex phenomena across the science fields, i.e. enable interdisciplinary research.

This session aims at discussing science cases, campaigns, or science demonstrators where several Earth system scientific disciplines were brought together to create new interdisciplinary insights.

We seek a breadth of contributions focusing on:

  • current conditions, opportunities and/or obstacles for realizing interdisciplinary research,
  • the process from starting to think across boundaries to the actual implementation of the interdisciplinary science campaign,
  • initiatives supporting the interdisciplinary research including concrete examples of their activities (technological, policies, funding schemes, etc.),
  • cases of successful interdisciplinary research collaborations showing results that were achieved by this collaboration.

Abstract submission

Observations and simulations of the terrestrial carbon and water budget are fundamental to understanding biosphere-atmosphere interactions under a changing climate. Multiple processes determine how mass and energy exchange scale from the level of a leaf, to the whole plant, to the ecosystem level, and to the globe. Empirical studies are subject to the level at which observations are collected, and models imply a choice regarding the scale for which predictions are representative. Recent research has revealed systematic differences between observations taken at different levels, e.g., regarding exchange fluxes of carbon and water between the biosphere and the atmosphere. This can add to model-data mismatch and limits process understanding.

This session aims at bridging terrestrial ecosystem observations across multiple temporal and spatial scales and from multiple variables. We particularly invite research with a focus on how we can learn from multiple observations of carbon and water exchange fluxes.

We encourage contributions with a focus on process modelling, machine learning, or with an empirical focus that aims at learning from parallel measurements, captured at the leaf (e.g. gas exchange), tree (e.g. sap flow and tree growth, dendroecology), and/or ecosystem level (eddy covariance towers, UAVs, aircrafts and satellites).

Abstract submission 



Managed agricultural ecosystems (grassland and cropland) are an important source and/or sink for greenhouse gases (GHG) as well as for reactive trace gases. Due to the simultaneous influence of various environmental drivers and management activities (e.g. fertilizer application, harvest, grazing) the flux patterns are often complex and difficult to attribute to individual drivers. Management related mitigation options may often result in trade-offs between different GHG or between emission of GHG and reactive gases like NH3, NO, or VOCs.

The session addresses experimentalists and modelers working on carbon and nitrogen cycling processes and related fluxes on plot, field, landscape, and regional scale. It is open to a wide range of studies including the development and application of new devices, methods, and model approaches as well as field observations and process studies.
Particularly welcome are studies on the full carbon, nitrogen or GHG budgets, as well as studies comparing GHG and reactive gas exchange. We also encourage contributions about emission factors for relevant gases.

Abstract submission




Being bullied or harassed at your workspace has a tremendous impact on both the professional and the personal wellbeing of the person subjected to such treatment.
Which acts and behaviours classify as bullying and harassment? How can you recognize if you or a co-worker/friend are the target of bullying and harassment? How can you protect yourself and others from bullying and harassment? What can we all together do to stop harmful behaviours from individuals or overarching structures? What do institutions need to do in order to create a healthy and safe work environment?

These questions and more will be addressed during this ECS Great Debate, which shall raise awareness for the harmful effects of bullying and harassment in academia, provide clarity around this complex matter, and encourage people to speak up and take action against it. Through round-table discussions we will talk about what is needed to create a healthy, safe and inclusive work environment for everyone, where bullying, any form of harassment and intimidation have no place.
