CRUTEM4, HadCRUT4, HadSST3, HadEX, HadEX2, HadCRUH and HadAT have been moved to a deprecated datasets page. They are retained solely for the purposes of comparison to the current datasets.

Researchers at the Met Office Hadley Centre produce and maintain a range of gridded datasets of meteorological variables for use in climate monitoring and climate research. This site provides access to these datasets or, in some cases, links to other places from where where they can be obtained. Each data set is provided under specific licence terms – please check the terms and conditions for each data set before you use it.

Please note that this is not an operational service. This site is run by research staff with the primary aim of improving collaboration with fellow researchers. Everyone is welcome to use the site, and we aim to make it reliable, but it does not have the same level of support as the main Met Office website.

Met Office Hadley Centre climate model data are distributed through the Centre for Environmental Data Analysis. Please consider the use of these data resources in your work, if appropriate.
