Dr Douglas Clark
I am a land surface modeller with particular interests in hydrology and its interactions with other biogeochemical processes. Most of my recent work uses the JULES land surface model and tends to look at the large areas typical of climate models. In particular I am interested in:
My current or recent work includes:
1998 - present: Land surface modeller at CEH. Areas of activity have included: hydrology, land-atmosphere interactions, carbon and nitrogen cycles, development of JULES code and documentation.
1995-1998: PhD Meteorology, University of Reading
1994-1995: Research assistant, developing a model of continental-scale hydrology, University of Newcastle Upon Tyne
1993-1994: MSc Engineering Hydrology, University of Newcastle Upon Tyne
1990-1993: BSc Meteorology, University of Reading
