If you have a question about this talk, please contact Dr Alex Archibald.

The Filter Inlet for Gases and AER Osols (FIGAERO) coupled with the Aerodyne High Resolution (HR)-Time of flight (ToF)-Chemical ionisation mass spectrometer (CIMS) is a fairly novel technique that can provide quantitative trace gas and aerosol measurements as well as some fundamental properties of the measured aerosol. The University of Manchester FIGAERO – CIMS has now been used widely in chamber and ground based measurements and results from laboratory characterisation of the instrument as well as ground based field work results from the Amazon Rainforest, Brazil and Beijing, China will be discussed. As part of the recent NCAS project, the CIMS has also been certified and deployed on the FAAM Bae 146 Research aircraft for measurements of organics and their oxidation products, halogen species and other important species atmospherically. Preliminary analysis of trace gas measurements from this platform will also be presented from the North Atlantic Troposphere.
