Richard P. Allan

I am a Reader in Climate Science at the Department of Meteorology, part of the University of Reading with affiliation to NCAS Climate, NCEO, ESSC 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.

Please also see my previous home page at ESSC. A list of my publications stored on the University CENTAUR system is included below. For a full list, see my Publications page.
