Atmospheric Chemistry: HIRAC Group

The Highly Instrumented Reactor for Atmospheric Chemistry (HIRAC) is a NERC funded atmospheric simulation chamber developed to bridge the divide between the study of elementary reactions in the lab, and large scale field work. Unlike many other atmospheric simulation chambers HIRAC allows researchers the unique ability to control temperature, pressure and photolysis rates during experiments and to measure radical concentrations.

Just as the name suggests, HIRAC has a broad range of instrumentation based on different detection techniques so that we can accurately monitor the chemistry occurring inside the chamber. HIRAC has been funded to carry out a number of exciting and novel experiments to answer some of the important questions remaining in atmospheric chemistry. We also plan to use the chamber to test and develop field measurement techniques.

HIRAC is a member of the EUROCHAMP (Integration of European Simulation Chambers for Investigating Atmospheric Processes) network of European chambers.
