TOMCAT Modelling Group
We study the chemical and dynamical processes which affect the composition of the natural and polluted atmosphere from the surface to about 100 km. We develop and use detailed 3-D models and use observations from a wide range of platforms.
Our research is largely based around the TOMCAT global atmospheric chemical transport model (and variants), but we also develop and use chemistry-climate models and regional models.
These pages give information about current group members, a summary of the model, an overview of our research, a record of news items and some blogs. There is also an archive of pages from the group leader Martyn Chipperfield. Use the navigation bar at the top of page.

Changing Atmosphere Infrared Tomography Explorer (CAIRT)
Humankind will soon lose a great deal of vigilance over the ozone layer, which shields life on Earth from harmful solar radiation. The impending loss of NASA’s Aura and the Canadian Space Agency’s SCISAT satellites threatens scientists’ ability to closely monitor compounds that destroy ozone and alter stratospheric circulation. With no planned missions to replace...
Nordstream Pipeline
Group members, led by Chris Wilson, join UN led collaboration to measure methane emissions from the 2022 Nord Stream Pipeline Leak – largest ever leak of methane recorded We employed the atmospheric chemistry transport model, TOMCAT, to track the methane plume over 1,500 km back to its source and produce an estimate of the leak...
Mayor of West Yorkshire meets Emily Dowd
The Mayor of West Yorkshire, Tracy Brabin, fulfilled an ambition by meeting PhD student Emily Dowd at the university. Mayor Brabin was on campus to attend the launch of the UK Earth Observation Network for Sustainability (UK-EONS) and was delighted to secure an unexpected photo with Emily. In her speech the Mayor paid tribute to...
