Project Overview


  • Field characterisation of a novel chemical ionisation mass spectrometer (CIMS) in an ammonia measurement intercomparision at an agricultural site near Edinburgh.
  • Measurements of the kinetics of non-biogenic (terminal and chlorinated) and biogenic (sesquiterpenes) alkene ozonolysis rate coefficients employing the EXTRA chamber and a GC-FID.
  • Measurements of the formic acid yield from the ozonolysis of isoprene using CIMS
  • Charecterising the kinetics of trace gas adsorption onto common inlet materials used in field measuremets.
