The theme of this conference is “the sustainable development goals”. The Cambridge dictionary defines sustainability as “the quality of being able to continue over a period of time”.

The 2019 coronavirus outbreak has forced us to drastically limit our mobility and thereby affected the way we live and work. As much as we would like to go back to normal, we may as well take a moment to reflect on the sustainability of that status quo. Not just because the root sources for a potential new outbreak have not been taken away, but also because the rapid adaptation to this new situation may have created opportunities for structural change.

In this special session we will ask ourselves how we, as a scientific community, can make our everyday research practice more sustainable and resilient.

Which elements of the former status quo do we really want to get back, and which of the new (digital) possibilities do we embrace? Should we foster the possibility of online or hybrid conferences? Maybe we can move all presentations to youtube, so that conferences can focus more on discussion and collaboration? Will our new digital teaching materials change the way we teach in the classroom? Do we keep our home offices and transform the office buildings to meeting spaces? Will international collaboration be boosted by improved online meeting platforms?

And how do we, as a community, respond to global threads like climate change or a virus outbreak? Should we limit our mobility for good? What expertise (e.g. data-assimilation, uncertainty communication) do we have that can help to provide rapid insight into global crises, and how do we make sure other fields also have access to our data, knowledge and methodologies? What other risks can we identify, and how can we best prepare for those risks? When it comes to climate change, what can we learn from the global responses to this more abrupt global crisis?


This is planned to be an interactive session in which we try to gather as much input as possible from the participants, and also encourage lively discussions and debates. With a very short introduction to spark off ideas and interest and explain the concept, the various topics are then discussed in smaller groups in break out areas.
At the end a short plenary wrap up could collect the ideas; key points that came out could be exhibited during the remainder of, or after the conference.

A substantial part of the national gross product in many countries is weather dependent. National weather services and the private sector have been innovative for more than a century to make better use of our meteorological knowledge. However, large gains are still to be made and this prize encourages individuals and groups to come with ideas how meteorology in a practical way can further move society forward. Meteorology can make society safer, can deliver costs savings and can bring more welfare to large groups of people. More information about the Prize and the Foundation can be found at

Applications for the 2021 Harry Otten Prize were possible until March. The jury selects three finalists who will give presentations at the EMS Annual Meeting explaining their ideas. The prize winner will be announced in the Awards Session on Tuesday 7 September 2021.

Professor Sergej S. Zilitinkevich (born in 1936 in Leningrad), our long-standing convener of the Boundary Layer Session at EMS, passed away on February 15, 2021. He will be remembered for his pioneering work in the physics of atmospheric turbulence and planetary boundary layers, but also for the energy and passion he displayed in all aspects of his work and last not least his unique personality. He was always developing new ideas even in his 80s.
This special session will bring some of co-workers along his career to bring forward some of his main contributions to science together with some personal memories and experience about working with him.
All participants to the session are welcome to air their own memories about Sergej, or how his ideas and papers may have influenced their work.

The indicative content will be:
Sylvain Joffre: Intro
Dmitrii Mironov: PBL depth
Christof Lüpkes: Nonlocal parametrization of turbulent fluxes
Yulia Troitskaya: Air-sea interaction
Alexander Baklanov: Air quality and urban parametrisations
Markku Kulmala: The Pan-Eurasian Experiment (PEEX)
Igor Esau: Climatic implications of the PBL turbulence
Free discussion involving the whole audience

Public information:

Unfortunately, this year's EMS has to take place in a virtual format. Due to the Corona pandemic, opportunities for early career scientists (ECS) to meet new people at live conferences have diminished over the past year. Therefore, we would like to organise an ECS icebreaker at the start of the conference to counteract for this deficit. This event will be hosted by the MeteoXchange project. This project has the following objective: strengthening atmospheric exchange processes - an international network for meteorologists.

At the beginning of the event, different countries or their meteorological societies will have the opportunity to briefly present research opportunities in their countries in the field of meteorology to give young scientists an insight into the many different projects and possibilities. Afterwards, there will be the opportunity to meet and exchange ideas in an informal atmosphere. We therefore encourage all ECS to attend this event to meet other young scientists before the session programme starts. 

The icebreaker will take place in in the Events room.

They review the progress or lack thereof made during the past three decades in efforts to create gender balance and equality in the global weather enterprise – how far have we come? How far do we still have to go?

The EU has recently adopted its new Framework Programme for Research & Innovation called Horizon Europe (HE) with a budget of 95 billion euros over 7 years (2021-2027). It includes many fundamental and application science areas where the meteorological and climate community at large can contribute to and benefit from funding.

The event will include an introduction by Dr. Adrian Broad (UK Met Office and EUMETNET) to the three pillars of HE, followed by more insights for our community into the most relevant clusters and connections with the important HE missions. This will include among others: climate systems and extreme weather; sustainable and intelligent transport systems in the air, on the road or seas; space weather and earth observation; renewable energy and agriculture sectors; the ocean and marine environment; heat waves and air pollution impact on health; technology and the digital economy; or safe systems for critical infrastructures. To conclude, links between HE and other relevant EU programmes will be made, focussing on Copernicus, Digital Europe and the Civil Protection Mechanism.

Afterwards, the floor will be open for questions from the audience.

Public information:

Julia Schmale is assistant professor at École Polytechnique fédérale de Lausanne, Switzerland, where she heads the Extreme Environments Research Laboratory (EERL) since 2019. Her research focuses on how the ocean, land, cryosphere and human activities influence the chemical and microphysical composition of the atmosphere, and the resulting effects on climate and air quality. The main study regions are the Arctic, Antarctica, Southern Ocean and high altitudes, where she deploys aerosol and trace gas instrumentation on aircraft, research vessels, ground-based observatories and tethered balloons. Prior to founding the EERL, Julia was part of the Laboratory of Atmospheric Chemistry at the Paul Scherrer Institute, Switzerland, where she started as a postdoc and then headed the molecular cluster and particle processes research group.
Throughout her career, Julia has been engaged in science-policy interaction, a direction she pursued in particular as scientist at the Institute for Advanced Sustainability Studies, Germany, after having obtained her PhD from the Max Planck Institute for Chemistry, Mainz, Germany. Currently Julia represents Switzerland in the international steering group of the MOSAiC expedition, the Atmosphere Working Group of the International Arctic Science Committee, and she is a lead author on the forthcoming report by the Arctic Monitoring and Assessment Programme’s expert group on short-lived climate forcers.

Julia Schmale will give the Keynote Presentation of the Programme Stream Understanding Weather & Climate Processes:
