Copernicus Climate Data Store: making climate information accessible to all

The Copernicus Climate Data Store is one of Europe’s most important resources for climate information, providing free access to a wealth of data, tools and applications. Developed as part of the European Union’s Copernicus Climate Change Service , the platform brings together climate observations, reanalysis products, seasonal forecasts and climate projections in a single location. By offering reliable and accessible information on past, present and future climate conditions, the Climate Data Store supports researchers, policymakers, businesses and citizens in understanding climate-related challenges and making informed decisions. 

The Climate Data Store provides access to datasets covering a wide range of topics, including temperature, precipitation, atmospheric composition, sea ice and extreme weather events. Among its most widely used resources is the ERA5 reanalysis dataset, which combines historical observations with advanced modelling techniques to create a comprehensive picture of the Earth’s climate. Users can explore data directly through the platform, visualise trends and download information for further analysis. This helps support activities ranging from climate research and urban planning to agriculture, renewable energy development and disaster risk management. 

The platform is also a strong example of the value of open data in action. By making high-quality climate information openly available, the Climate Data Store encourages transparency, collaboration and innovation across Europe and beyond. Open access to climate data enables organisations to develop new services, improve environmental monitoring and create data-driven solutions to address climate change. It also helps ensure that scientific knowledge can be shared and reused widely, supporting evidence-based policymaking and public awareness. 

To discover how climate data can support your work or research, explore the Copernicus Climate Data Store and browse the growing range of climate datasets available. You can also find additional environmental and Earth observation resources through the European Data Portal, helping you unlock the full potential of open data for a more sustainable future.
