Methods and Analysis
The Met Office maintains historic climate records and series, which are used to monitor the climate of the UK at a national and regional level
Generation of monthly and annual long-term averages
Monthly and annual long-term average data sets 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 1 x 1 km grid of points covering the UK.

Generation of monthly and annual gridded data sets
Monthly 5 x 5 km gridded data sets covering the UK have been been produced from 1910 for air temperature and rainfall amount, from 1929 for sunshine duration, and monthly and annual gridded data sets from the 1960s for around 30 other climatic parameters. 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 Defra, and are freely available for research purposes.
The monthly and annual gridded data sets have been analysed to investigate trends in the UK climate since 1914 (or 1961 for some variables).
