Monthly and annual long-term average datasets of 13 climate variables were generated for the periods 1961-90 and 1971-2000 using a consistent analysis method. Values were produced for each station in the Met Office’s observing network and for a rectangular grid of points covering the UK at a horizontal spacing of 1km.

Climate statistics for the periods 1961 to 1990, and 1971 to 2000

Monthly and annual 5 km x 5 km gridded datasets covering the UK have been generated for the 1961-2000 period, for 36 climatic parameters. These datasets are used to place individual months into context. The same analysis methods are employed in the production of monthly and seasonal summaries.

A number of the climate variables have been produced with funding from the UK Climate Impact Programme (UKCIP), and are freely available for research purposes.
