TheMet Office Hadley Centre — named in honour ofGeorge Hadley — is one of theUnited Kingdom's leading centres for the study of scientific issues associated withclimate change. It is part of, and based at the headquarters of theMet Office inExeter.

The Hadley Centre^[1] was founded in 1990,^[2] having been approved by the then British Prime MinisterMargaret Thatcher and was first named theHadley Centre for Climate Prediction and Research but subsequently renamed on various occasions.^[3][4]

The centre has several major aims:

• To understand physical, chemical and biological processes within the climate system and develop state-of-the-artclimate models
• To use climate models to simulate global and regional climate variability and change
• To predict inter-annual to decadal variability of climate
• To predict long term climate change
• To monitor global and national climate variability and change
• Toattribute recent changes in climate to specific factors

The 30th anniversary of the Hadley Centre was celebrated in 2020.^[5]

The Met Office employs over 1500 staff, with approximately 200 working in its climate research unit. Most of its funding comes from contracts with theDepartment for Environment, Food and Rural Affairs (DEFRA), other United Kingdom Government departments and theEuropean Commission. It also works closely with theIntergovernmental Panel on Climate Change (IPCC) providing worldwide climate forecasting and predictions.

The climate model (HadGEM) developed by the centre is used for climate change research purposes across the world. It covers both Ocean modelling and Atmospheric Modelling. Collecting data from across the world.^[6]

The UK Climate Prediction Project uses the Hadley Centre climate model projections of future UK climate to inform UK government policy.

The Australian Bureau of Meteorology and the Korean Meteorological Agency use the Hadley Centre GloSea5 system for long range prediction.

Thevolunteer computing projectClimatePrediction.net is a research team based at theUniversity of Oxford conducting research into global climate change using adapted versions of theclimate models developed at the Hadley Centre. Individuals can participate in the research efforts by donating spare computer resources to aid their research.

ThePRECIS (Providing Regional Climates for Impacts Studies) project enables scientists from the around the globe to run a regional climate model towards carrying out research into climate change.
