HadUK-Grid is a new collection of gridded climate variables derived from the network of UK land surface observations. The data have been interpolated from meteorological station data onto a uniform grid to provide complete and consistent coverage across the UK. The data sets cover the UK up to 1km x 1km resolution and a range of other resolutions to allow for comparison to data from climate projections and across a country, administrative regions and river basins. The dataset spans the period from 1862 to present, but the start time is dependent on climate variable and temporal resolution. The grids are produced for daily, monthly, seasonal and annual timescales, as well as long term averages for a set of climatological reference periods. Variables include air temperature (maximum, minimum and mean), precipitation, sunshine, mean sea level pressure, wind speed, relative humidity, vapour pressure, days of snow lying, and days of ground frost.
This data set will supersede the UKCP09 gridded observation. The primary purpose of these data are to facilitate monitoring of UK climate and research into climate change, impacts and adaptation. The datasets have been created by the Met Office with financial support from the Department for Business, Energy and Industrial Strategy (BEIS) and Department for Environment, Food and Rural Affairs (DEFRA) in order to support the Public Weather Service Customer Group (PWSCG), the Hadley Centre Climate Programme, and the UK Climate Projections (UKCP18) project. The data recovery activity has also been funded by the Natural Environment Research Council (NERC grant ref: NE/L01016X/1) project “Analysis of historic drought and water scarcity in the UK”. The dataset is provided under Open Government Licence.
