ACCORD - a consortium for the development of a regional weather forecast model

ACCORD is a consortium of 26 countries in Europe and North Africa jointly developing a numerical computational model for regional weather forecasting.

The ACCORD consortium was established in 2020 as a further development of the collaboration between the ALADIN, LACE and HIRLAM consortia for regional numerical weather prediction systems. The ACCORD consortium will strengthen cooperation on research and development of a computational model focusing on short-term weather forecasts for the next 1-3 days. The aim is to enable national weather institutes to deliver improved forecasts to society and achieve a deeper understanding of the processes that are most important for predicting weather phenomena on short time scales. This will help protect life and property during extreme weather events and support well-being.

The first phase of the collaboration runs 2021-2025 and is led by a strong international management team of nominated researchers. Researchers from SMHI have important positions in the ACCORD management team in the form of leaders for the areas of Atmospheric Physics and Ground Processes. SMHI also leads the work on data assimilation and the use of observations within HIRLAM.

ACCORD works closely with the European Satellite Organisation EUMETSAT, the European Meteorological Observation Network EUMETNET and the European Centre for Medium-Range Weather Forecasts ECMWF.

The 26 countries in the consortium are Algeria, Austria, Belgium, Bulgaria, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Hungary, Iceland, Ireland, Lithuania, Morocco, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Tunisia and Türkiye.
