The University of Manchester Centre for Atmospheric Science owns and operates an instrumented aircraft designed for atmospheric research. The aircraft, a Cessna 182J, is equipped with sophisticated turbulence, trace gas, aerosol and cloud microphysics instrumentation to make a wide range of atmospheric boundary layer measurements. It is based at Liverpool Airport and has access to a wide range of technical support facilities. Dr Ann Webb, a member of the centre's academic staff, is responsible for the aircraft and is also the main pilot. The aircraft is used by students as part of their PhD research and has participated in a number of UK research programmes. The aircraft was fitted with a new data system, and several new instruments, as part of the NCAS Facility for Ground-based Atmospheric Measurement (FGAM).
