We characterised trace gas emissions from Australian temperate forest fires through a mixture of open-path Fourier transform infrared (OP-FTIR) measurements and selective ion flow tube mass spectrometry (SIFT-MS) and White cell FTIR analysis of grab samples. We report emission factors for a total of 25 trace gas species measured in smoke from nine prescribed fires. We find significant dependence on modified combustion efficiency (MCE) for some species, although regional differences indicate that the use of MCE as a proxy may be limited. We also find that the fire-integrated MCE values derived from our in situ on-The-ground open-path measurements are not significantly different from those rep..

For the NSW fires, the authors would like to acknowledge Sharon Evans, Bill Sullivan and Simon Hawkes from the New South Wales National Parks and Wildlife Service for allowing us to make measurements at their prescribed burns and providing copies of their burn plans. Thanks are also due to Melanie Cameron, Dagmar Kubistin, Paul Taglieri and Rachel Stevens from the University of Wollongong and Grant Edwards and Cheryl Tang from Macquarie University for help with grab sample collection. For the fires in Victoria, we thank Elizabeth Ashman from the Department of Environment, Land, Water and Planning as well as Doreena Dominick and Kaitlyn Lieschke from the University of Wollongong. We would also like to acknowledge Travis Naylor and David Griffith for helpful MALT discussions and Graham Kettlewell and Martin Riggenbach for technical support.
