During the SHIVA (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere) campaign in Nov. and Dec. 2011, polluted air masses were observed in the marine and terrestrial boundary layer (0 – ~2 km) and in the free troposphere (~2 – 12 km) over Borneo/Malaysia. The measurements include CO, CO2, CH4, N2O, NO2, and SO2 as primary pollutants, O3 and HCHO as secondary pollutants, and meteorological parameters. This set of trace gases combined with a Lagrangian particle dispersion model (e.g., FLEXPART) and emission inventories are used to fingerprint different sources (e.g., biomass burning) of local and regional air pollution.

The long-term trend and seasonal variation of biomass burning emissions in this region are first presented and discussed based on the FINN inventory the FLEXPART simulation. Results highlighted the recurrent influence of palm plantation fires near the Miri airport, allowing regular sampling of this fire at different age plumes. The study of the emission ratio compared to CO2 or CO can be used as a measure of combustion efficiency to help define the type of biomass burning. Additionally, the age of plume sampled by the aircraft measurement is determined by FLEXPART and compared with the ΔO3/ΔCO ratio measured in this study and bibliographic database in order to study the ozone production during the transport of biomass burning plumes and implement such database with palm fire data.
