Partner 15 - MetO (United Kingdom)
UK MetOffice (MetO)

Expertise and experience of the organization
The Met Office has well over 20 years of world-leading expertise in climate modelling. Currently 150 scientists research climate science in the Met Office’s Hadley Centre for Climate Change. The fields represented include climate monitoring, climate modelling, climate variability, quantifying uncertainty, understanding climate change, and climate-chemistry-ecosystem feedbacks. Research on atmospheric composition and climate includes global modelling of aerosol and gas-phase reactive chemical constituents. The focus here is on the direct and indirect radiative and climate impacts of these constituents through their interactions with clouds, terrestrial and ocean ecosystems and the land surface. The atmospheric composition team are currently participating in the EU projects EUCAARI, ACCENT and GEMS.

Role and contribution

The Met Office will co-lead WP6 and will contribute significantly to WP5. In WP6 the Met Office will lead the work on global climate effects of megacities and will contribute with its HadGEM2 climate model which includes the UKCA package of interactive aerosols and reactive gases. In WP5 the Met Office will contribute to tasks 5.5 and 5.6.

Principal personnel involved
Dr. William Collins - Graduated from the University of Cambridge with a degree in Natural Sciences and a PhD in Particle Physics. He holds an MSc in Weather and Climate from the University of Reading. He has worked in the Met Office for since 1993 and with others built the Met Office tropospheric chemistry transport model. He is involved in the EU EUCAARI project and has previously been involved in STACCATO. He has contributed as a co-author to the IPCC third assessment report, and as an expert reviewer to the IPCC forth assessment report. He has authored, or co-authored over 40 peer-reviewed papers.
Dr. Olivier Boucher - Olivier Boucher gained a PhD in Physics in 1995 and an Habilitation in Physics in 2003. He was a junior scientist at the Centre National de la Recherche Scientifique (CNRS) from 1996 to 2005. He is now a senior scientist at the CNRS on secondment to the Met Office which he joined in 2005 as Head of the “Climate, Chemistry, Ecosystems” team. His main speciality is the study of the climatic effects of aerosols in relation to radiation and clouds. Olivier has been a lead author in the IPCC Special Report on Aviation and the Global Atmosphere and the IPCC Working Group I Third Assessment Report.
Dr. Michael Sanderson, - D.Phil in Atmospheric Chemistry (1994) has published over 20 articles in peer-reviewed literature in the field of atmospheric chemistry. Research work has included, modelling of global trace gas concentrations, and atmosphere-biosphere interactions. The impact of climate change on these processes is also a major feature of his research work. Has participated in several international projects, ACCENT Photocomp, TF HTAP and Greencycles. Has also worked on contracts with the UK Defra, using various model experiments to answer policy-relevant questions concerning possible emission changes and related air quality changes.
M. Shekar Reddy - Areas of interest include the emissions inventory development, and modelling of atmospheric transport of aerosols and their climate impacts from regional to global scales.  He has expertise in development technology of based emissions inventories for the south Asian region and regional climate impacts. He is a contributor to international aerosol intercomparison project.
