Job Description
The Role
We are looking for a talented Machine Learning Scientist to spearhead exploratory development of an AIFS atmospheric composition forecasting model. The successful candidate will be embedded into both CAMS and AIFS teams and be supported by domain experts from both disciplines. They will explore how the AIFS should be adapted and trained to leverage atmospheric composition datasets, particularly analysis and reanalysis datasets. They will be at the forefront of understanding the role of machine learning for atmospheric composition forecasting.
The Challenge
ECMWF is building a world-leading, machine learning based probabilistic weather forecasting system (AIFS), to complement our existing physics-based system (IFS). We are pioneering the operationalization of machine learning forecasting models in this domain. ECMWF now runs both deterministic and probabilistic AIFS forecasts daily, providing open data and products to users around the world.
Global atmospheric composition forecasting with the IFS is also a key service of ECMWF. The forecasts are 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). Early results in the scientific literature suggest that data-driven forecasting could be a valuable contribution to the operational forecasting of atmospheric composition.
ECMWF will expand the scope of the AIFS and explore how data-driven forecasting can complement physical and chemical models in producing impactful operational forecasts of atmospheric composition. The operational CAMS forecasting system is used for the monitoring and forecasting of air quality, monitoring the ozone layer, and increasingly the monitoring of anthropogenic emissions of greenhouse gases.
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 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 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.
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. We appreciate the need for flexibility in the way our staff work. We have adopted a hybrid work model that allows flexibility to staff to mix office working and teleworking, including away from the duty station for up to 10 days/month (within the area of our member states and co-operating states).

The Copernicus Atmosphere Monitoring Service
Over the years, ECMWF has also developed a strong partnership with the European Union, and for the past seven years has been an entrusted entity for the implementation and operation of the Climate Change and the Atmosphere Monitoring Services of the EU Copernicus Programme, as well as a contributor to the Copernicus Emergency Management Service. The collaboration does not stop there and includes other areas of work, including High Performance Computing and the development of digital tools. It is enabling ECMWF to now provide data and products covering weather, climate, air quality, fire and flood prediction and monitoring.
The Copernicus Atmosphere Monitoring Service (CAMS) 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 . The question of the environmental impacts on human health has received growing interest in recent years, in particular during the COVID-19 crisis. The UN World Health Organisation estimates that over 7 million people worldwide (over 400.000 in Europe) die prematurely due to insufficient air quality. Improving the estimates of the exposure of populations to the main pollutants is a key objective for CAMS in order to increase awareness and support the development of more protective public policies. Another key topical area of CAMS is the estimation of emissions of greenhouse gases using observations in the atmosphere: this is essential to quantify the effectiveness of mitigation policies and guide the development of new ones at city, regional and country level.
