Richard P. Allan

I am professor of Climate Science at the University of Reading Department of Meteorology. My research is driven by the fundamental question: how much will Earth warm in the current century and what are the implications for the global water cycle, upon which societies and ecosystems depend? I use Earth Observation data to explore fluctuations in clouds, water vapour, rainfall and the Earth's radiative energy balance and use this information to assess the realism of climate prediction models and improve our understanding of the climate system. I am a lead author for the Intergovernmental Panel on Climate Change 6th assessment report (AR6)

I have been Principal Investigator on a number of projects, including the recent NERC DEEP-C consortium. I am affiliated with National Centre for Earth Observation and the Walker Institute and have previously been a member of NCAS Climate and the Met Office.
