The HAPPI project is coordinated at Oxford and Bristol Universities. If you would like to get involved, please contact Dann Mitchell ( and/or Lauren Brown ( Updates will also be sent through twitter, please follow @ClimateDann. We encourage anyone interested in using the data to understand the changing climate to get in touch.

Publication policy: A tremendous amount of work has gone into the experimental design and simulation of data for HAPPI. As such, any authors publishing with the data within the first year of generation should offer co-authorship to the relevant scientists (papers submitted before the 30th of November). Only one scientist from each modelling centre need be asked, and this applies to the bias-corrected ISI-MIP data as well. If HAPPI data are not integral to the research paper, then we leave it to the lead author to decide if this policy is relevant. Please get in touch to find out who they are. We will also add the publications to our Publications page when accepted by the journal.
