Abstract
Biogenic emissions from plants are important components of the Earth System that can affect regional air quality or climate significantly. Plants emit much more biogenic VOCs into atmosphere compare to human activities; especially during extend warm weather. Therefore the objectives of this study are to study the effects of land cover change to the biogenic emissions specifically on isoprene in Borneo for the present day (2000 to 2010) and the future (2090 to 2100) climate scenarios, the effects of the climate change on Borneo to the isoprene emissions for the present day (2000 to 2010) and the future (2090 to 2100) climate scenarios and the effects of combined land cover change and climate change to the emissions of isoprene for the present and future day. PRECIS, the regional climate model used in this project, is an atmospheric and land surface model of a limited area with a horizontal resolution of 0.440 x 0.440 (50 km x 50 km). Meanwhile, Biogenic Volatile Organic Compounds Emission Model (BVOCEM) was used to estimate biogenic emissions. The emissions of isoprene were compared with Oxidant and Particle Photochemical Processes (OP3) in Danum Valley. The total biogenic emission of isoprene were mainly affected by climate or atmospheriC change alone and combined atmospheric and land cover change. The impacts of land cover change are less significant compared with atmospheric forcing and combined of atmospheric and land cover forcing. In comparing atmospheriC forCing alone and combined forcing, atmospheric forcing alone showed slightly more impacts to the emission of isoprene.
