Climate monitoring and data sets

The Met Office Hadley Centre monitors a broad range of climate variables and indices. These are used worldwide for climate monitoring and climate modelling and in studies of the causes of climate change.

Our work features prominently in many influential reports such as the Intergovernmental Panel on Climate Change reports and the Stern review and also in prominent scientific papers.

The Met Office Hadley Centre makes the vast majority of its data sets freely available (for academic and personal use only). Commercial use is forbidden under the terms and conditions and commercial organisations should first contact the Met Office Customer Centre.
