UKCP09 gridded observation datasets

Gridded climate data for the UK interpolated from station observations.

Gridded data sets based on surface observations have been generated for a range of climatic variables and are available under open licence.

The primary purpose of this data resource is to encourage and facilitate research into climate change impacts and adaptation. The data sets have been created with financial support from the Department for Environment, Food and Rural Affairs (Defra) and are promoted within the UK Climate Projections (UKCP09). The UKCP09 report The climate of the UK and recent trends uses these gridded data sets to describe UK climatologies and recent regional trends. These datasets are being revised as part of the UKCP18 Project and support an annual State of the UK Climate publication.

The data sets cover the UK at 5 × 5 km resolution and span the period 1910–2016. They are available for daily, monthly and annual timescales, as well as long-term averages for the 1961–1990 climate baseline period. Baseline averages are also available at 25 × 25 km resolution (to match the UKCP09 climate change projections) and as regional values.

Data Licence: The UKCP09 observational datasets are now all available under Open Government Licence. Before using these data please ensure you have read and understood these licence terms.

NEW (08/2017): The UKCP09 observational datasets have been migrated to a new archive at the Centre for Environmental Data Analysis (CEDA). The updates include the addition of daily 5 km gridded precipitation and updates to the year 2016. The data are free to use but registration is required at CEDA for access.
