Chemical Transport Modeling

The members of the  Center for Atmospheric Chemistry are working with the state-of-art Global Chemistry and transport model GEOS-Chem to study the atmospheric chemistry and transport of tropospheric traces gases and aerosols from both natural and anthropogenic origin. The model simulations are carried on at the Australian Center for Advanced Computing (APAC) under a Merit Allocation Scheme grant "3-D Chemical Transport Modelling of Australian Biomass Burning Emissions". The CAC modeling capability is unique in Australia and the Southern Hemisphere. 

The present projects include:

• top-down estimation of emissions from 2003 Canberra megafires using satellite observations from MOPITT and MODIS .
• long range pollution transport of bush fire smog over the Tasman sea and in the South Hemisphere. The hemispheric transport of carbon monoxide taking place in the spring 2001 is seen on the animation
• estimation of soil NOx emissions from Australian desert (2008 honours project Penelope Kent) in collaboration with I. Galbally, Centre for Australian Weather and Climate Research.
• climate-chemistry interaction: role of Australian bushfires for the abundance of tropospheric ozone and aerosols 2025-2050 (in preparation for 2008 funding application)
