Research Area
The chemistry of the atmosphere is complex and vital for life on Earth. My research focusses on chemistry-climate interactions and Earth System Modelling, using the UK Earth System Model (UKESM) and the United Kingdom Chemistry and Aerosols (UKCA) modelling framework. I make use of large-scale high performance computing systems (HPCs) to simulate physical and chemical processes and their interactions within the atmosphere and with the Earth system to understand our past, current, and potential future climate. I am also involved in developing software tools and workflows to improve how global models make use of in-situ and remote sensing observations from various platforms such as satellites and research aircraft.
I work closely with the UK Met Office to develop and investigate new schemes and parameterisations for use in UKESM and I also develop UKCA to work on computing platforms that utilise GPUs in preparation for utilising exascale HPCs. This work is part of the development of the Met Office’s next generation modelling system that will provide future weather and climate modelling capability for the UK. We make use of computing facilities within Cambridge as well as national HPC resources for performing simulations and analysing model output.
Project Interests
I am particularly interested in lightning and its impact on the Earth system, specifically on atmospheric ozone. This project would involve working closely with the UK Met Office and would utilise measurements taken by the BAe-146 aircraft of the FAAM Airbourne Laboratory to develop new lightning parameterisations within UKESM.
I am also involved with developing UKCA to work on exascale computing systems as part of the Met Office’s next generation modelling system. This involves implementing the model on graphics processing units (GPUs) to improve performance of the complex chemical and aerosol processes that are being simulated.
