The first main task of this project is to investigate climate change in Southeast Asia using WRF Model at a higher resolution project, with aim of developing climate change scenarios (RCP4.5, 6.0, and 8.5) for the region. The output would help to identify which areas in the region that potentially important in assessing climate vulnerability for adaptation purposes. The second task is to develop biomass burning emission inventory for the whole of Southeast Asia. This region is prone to forest fire especially the tropical forest over Borneo Island, Sumatera Island as well as savannah forest over continental Southeast Asia (Indochina). For this investigation the year 2013 was selected as it was considered a neutral year. The inventory of biomass emission is important as an input for the air quality model of the region. The third task is developing the biogenic emission inventory for Southeast Asia. The main compound in the investigation was isoprene as it is very reactive and important in atmospheric chemistry, particularly on ozone chemistry and secondary aerosol formation. The last task was to investigate the regional air quality (ozone and other pollutants) under climate change scenarios. Four workshops and research meetings were organised as part of the commitment to disseminate information on the research focus to the collaborating countries.
