Your role

We have a new role for a Scientist (A2) in the Atmospheric Composition Section of the Research Department, to be based in our office in Bonn, Germany. The operational forecasting of atmospheric composition with ECMWF’s Integrated Forecasting System (IFS) is a core component of the Copernicus Atmosphere Monitoring Service (CAMS). The IFS is today one of the most comprehensive and advanced systems in the world for data assimilation and forecasting of global atmospheric composition, with operational outputs serving hundreds of users daily and being seen by millions (for instance through CNN, Windy, and other platforms).

You will contribute to the further development of the atmospheric composition modelling code of the IFS. The IFS includes specific schemes for the modelling of aerosols, chemical species, and some of the major greenhouse gases. To further improve these schemes and their interaction with the meteorological model components, you will work in close collaboration with staff at ECMWF but also with external partners. Most of these partner contributions are delivered through externally contracted activities as part of the CAMS programme, which are guided by ECMWF staff. Your role will ensure that the atmospheric composition modelling in the IFS and therefore the daily CAMS global forecasts will remain and define the state of the art.

About the Section

The Atmospheric Composition Section oversees the development of the atmospheric composition aspects in the IFS. The role will require significant engagement with Section members and other IFS developers, externally contracted research scientists, and colleagues throughout ECMWF.

About ECMWF

The European Centre for Medium-Range Weather Forecasts (ECMWF) is a world-leader in weather and environmental forecasting. As an international organisation we serve our members and the wider community with global weather predictions and data that is critical for understanding and solving the climate crisis. We function as a 24/7 research and operational centre with a focus on medium and long-range predictions, holding one of the largest meteorological data archives in the world. The success of our activities builds on the talent of our scientists and experts, strong partnerships with 35 Member and Co-operating States and the international community, some of the most powerful supercomputers in the world, and the use of innovative technologies and machine learning across our operations. ECMWF is a multi-site organisation, with a main office in Reading, UK, a data centre/supercomputer in Bologna, Italy, and a large presence in Bonn, Germany.

ECMWF has also developed a strong partnership with the European Union and has been entrusted with the implementation and operation of the Destination Earth Initiative and the Climate Change and Atmosphere Monitoring Services of the Copernicus Programme. Other areas of work include High Performance Computing (HPC) and the development of digital tools that enable ECMWF to extend provision of data and products covering weather, climate, air quality, fire and flood prediction and monitoring.

About Copernicus

Copernicus is the earth observation component of the European Union (EU) space programme. Based on the exploitation of spaced based and in situ (earth-based) observations and scientific models, Copernicus provides information services for land, marine, atmospheric and climate monitoring, as well as emergency management and security. These services, and their free, open and quality assured data and tools, support a range of environmental and security applications across sectors and policy domains. For details, see www.copernicus.eu

The Copernicus Atmosphere Monitoring Service (CAMS) service provides consistent and quality-controlled information related to air pollution and health, solar energy, greenhouse gases and climate forcing, everywhere in the world. For details, see https://atmosphere.copernicus.eu

The Copernicus Climate Change Service (C3S) service provides authoritative information about the past, present and future climate, as well as tools to enable climate change mitigation and adaptation strategies by policy makers and businesses. For details, see https://climate.copernicus.eu
