Current activities

Justin is a Senior Scientist in the OBR Group. His work spans the development of new instrumentation for aerosol measurements, involvement in atmospheric field measurement campaigns, and use of aircraft data to test and improve the performance of aerosol schemes in atmospheric climate and weather models.

Justin is currently leading a project to build a new state-of-the-art spectroscopic instrument to characterise aerosol optical and physical properties aboard the FAAM BAe-146 research aircraft. This instrument will be used for first scientific field measurements in 2016.

Justin is also involved in the analysis of data collected during SAMBBA, an aircraft-based campaign that measured biomass burning emissions over the Amazon during 2012. He is working with members of the Earth Systems Science and Mitigation Aerosol Modelling group to test the performance of different aerosol schemes used in the Met Office global climate model.

Career background

Justin joined the Met Office OBR Group in 2013. Prior to this he spent 4 years as a Research Scientist at the NOAA Chemical Sciences Division in Boulder CO, USA. He worked on the development and use of advanced spectroscopic instruments for aerosol property characterisation and was involved in numerous laboratory- and aircraft-based experiments. Justin used data from these experiments to investigate the impacts of aerosol on atmospheric radiation transfer.

Justin received a PhD from the University of Cambridge in 2009. During his PhD, he developed a novel broadband spectroscopy technique for measuring reactive trace gases in the atmosphere. He used the technique to study a range of chemical systems impacting air quality. Prior to this, he received a first class MSci degree in Natural Sciences (Physical Chemistry) from the University of Cambridge.
