Richard P. Allan

I am a Professor of Climate Science and joint head of the Department of Meteorology in the University of Reading with affiliation to NCAS Climate, NCEO and the Walker Institute.

My research is driven by the fundamental question:   How much will the 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 the Principal Investigator on the NERC - DEEP-C project. My publication list is stored on the University CENTAUR system; for a full list, click the PUBLICATIONS tab on the left. Presentations can be accessed by clicking the TALKS tab.
