Campaign:  Chemical Ionisation Mass Spectrometer


Campaign acronym:  CIMS


Description:

A flying campaign to validate a new instrument to measure nitric acid and ammonia.

Overall aim: The installation, testing and demonstration of a Chemical Ionisation Mass Spectrometer on the UK FAAM aircraft that can measure nitric acid and ammonia with sufficient sensitivity to address many atmospherically important questions coupling the oxidation of oxides of nitrogen with the loss to aerosols. These problems dictate regional deposition and transport pathways and are of important regional air quality and climatic importance.
