My group's research focuses on the transport and chemistry of trace constituents
in the atmosphere, and their interactions with the Earth's biosphere
and climate system. We use models and observations to improve understanding of
these processes.
I am also Director of the Centre of Excellence for Modelling the Atmosphere
and Climate (CEMAC).
Recent work
Large inter-model diversity in NOy partitioning and oVOC abundances at high latitudes
Seasonal variation of zonal average concentrations of NOy species and oVOCs at 700 hPa,
averaged over 50–70◦ N latitude band from the POLMIP (POLARCAT Model
Intercomparison Project) models. Models show particularly large diversity in
their simulation of these sparsely-observed species, with important
implications for simulation of ozone in the Arctic troposphere. Excerpt from Figure 7 of Emmons
et al., (2015).

17 Nov 2016: PhD opportunity! Jointly with the Centre for Ecology and
Hydrology, we are hoping to recruit a well-motivated
and enthusiastic PhD student to work on understanding the combined impacts of
ozone pollution and drought on plants and their role in the water cycle. More information here.
Closing date: 9th Jan 2016.
