The PRECIS Regional Climate Modelling System

Welcome to the PRECIS website!

PRECIS stands for "Providing REgional Climates for Impacts Studies." 

 Developed at the Hadley Centre at the UK Met Office, PRECIS is a regional climate modelling system

designed to run on a Linux based PC.  PRECIS can be easily applied to any area of the globe to

generate detailed climate change projections.
