Recently, multiple research have highlighted important roles of BVOCs to understand regional air qualities of megacities in East Asian. The findings strongly urge multi-faceted research on emission and oxidation processes of BVOCs and potential impacts on regional air quality from the interactions between biosphere and atmosphere. To address these emerging research topics in a longer term, National Institute of Environmental Research of South Korea established a research site in the Taehwa Research Forest, located at the edge of the Seoul Metropolitan Area (population 25 million). A 40 meter high tower was built in a pine tree plantation (Pinus Koraiensis), surrounded by a natural broad leaf ecosystem. Three inlets were configured to characterize trace gas gradients, above canopy(40 m), top of the canopy (23 m) and inside of the canopy (5 m) and multi-level meteorological sensors include PAR sensors were set up. In the laboratory space, high-sensitivity Ionicon PTR-MS, and CO, NOx, SO2, and ozone analyzers are operational for continuous gradient measurements. We will present preliminary gradient measurements results of both antropogenic and biogenic VOCs to quantify emission and deposition potential of the compounds.In addition, ozone and their precursors such as CO, NOx measurement results at the site will be presented to discuss biosphere-atmosphere interactions and their impacts towards regional air quality.
