RODEO Project Launch – making meteorological high-value datasets available for all


The Provision of Open Access to Public Meteorological Data and Development of Shared Federated Data Infrastructure for the Development of Information Products and Services (RODEO) Project has now been officially launched.


In 2019, the European Commission issued a revised directive on open data (1024/2019/EU) which aims to harmonize and enhance regulation related to the opening of public sector data reserves. The Implementing Regulation of the Directive defines High Value Datasets (HVD), (EU) 2023/138, and the technical requirements for each of the data categories. One of which concerns meteorological data.

The RODEO project responds to the requirements of the HVD Implementing Regulation by making meteorological High Value Datasets easily available and bringing new data to businesses, public administrations and citizens.

The regulation defines requirements for surface weather observations, climate time series, warnings, weather radar data, and Numerical Weather Prediction (NWP) data. Furthermore, the regulation specifies they shall be available under an open license, in a machine-readable format using Application Programming Interfaces (API) and bulk downloadable. These datasets will be free of charge.

The project is co-funded by the Digital Europe Programme (DIGITAL) and by the network of 31 European National Meteorological and Hydrological Services (EUMETNET). The project partners consist of 11 European meteorological institutions (listed below), the European Centre for Medium-Range Weather Forecasts (ECMWF) and EUMETNET..

The project strengthens the capacity of the European meteorological data providers to comply with the HVD Implementing Regulation by:

  • Developing a user interface
  • Developing APIs for accessing weather observation data, climate data, weather radar data, warnings, and AI datasets
  • Developing a data catalogue for making data discoverable
  • Engaging with the data owners and user communities
  • Supporting the deployment of national data portals and APIs
  • Making HVDs available from the project partners

During the three-year RODEO project, the project partners will design and implement harmonised technical solutions supporting the European meteorological institutions to meet the HVD requirements. This will increase the usability of public sector meteorological data and boost entrepreneurship, improve and develop digital products and services and support climate research.

Most importantly, better data availability leads to better weather warnings, forecasts, and services to the public and weather-critical industries, and contributes to the safe and efficient functioning of society with multiple benefits across the European economy, industry, and society.
