Abstract


  • The ‘Black Saturday’ fires were a series of devastating bushfires that burned across

    Victoria, Australia, during February 2009. The smoke plume from Saturday the 7th February,

    the worst day of the fires, separated from subsequent emissions and persisted for several

    weeks, providing the opportunity to track the changing composition of the smoke plume as it

    aged. In this study we have used satellite data from the Ozone Monitoring Instrument (OMI)

    and the Atmospheric InfraRed Sounder (AIRS) to characterise the emissions of formaldehyde

    and nitrogen dioxide from the fires. Emission ratios with respect to carbon monoxide are

    determined for formaldehyde (0.017 ± 0.004 mol.mol-1) and nitrogen dioxide (0.004 ± 0.001

    mol.mol-1). Additionally OMI UV Aerosol Index is used to track the smoke plume and infer

    how the concentration of these gases changes as the smoke ages. Our study suggests that

    formaldehyde concentrations within the smoke plume increase during the first day before

    declining to background levels within 2 days after emission. Nitrogen dioxide concentrations

    show a monotonic decrease reaching background levels about 1 day after emission.
