Characteristics of Baseline Greenhouse Gases in Western North Pacific(3/3)

The growing attention by the scientific community and general public has focused on the anthropogenic climate change as well as the rising concentration of greenhouse gases (GHGs), especially carbon dioxide in the atmosphere. In response to these environmental issues, the policymakers and their societal actions require a scientific understanding of the carbon cycle as a knowledge support for legislating and implementing adequate mandates. Meanwhile, as a result of rapid economic growth in East Asia over the past few decades, increased emissions of anthropogenic air pollutants have been transported by the Asian continental outflow, which in turn can alter the trace gas contents of Taiwan and even the Northern Hemisphere. To strengthen our understanding of this relatively pristine region receives polluted air masses via long-range transport pathways, multiple sampling locations, e.g. Lulin Atmospheric Background Station (23.47°N, 120.87°E; 2862 m a.s.l.)， Dongsha Island (20.70°N, 116.73°E; 8 m a.s.l.), Mt. Bamboo, Taiping Island, and Lanyu Island, will be served to investigate the seasonalities and changes of atmospheric greenhouse gases from the perspectives of concentration variations and average levels representative at different altitudes of this region.This study aims at integrating modern monitoring techniques to construct and perform the long-term continuous measurements of the baseline greenhouse gases in the atmosphere. The characteristics and patterns of the greenhouse gases will be also carefully assessed based on intensive measurements by using the aforementioned methods to provide the regional view of the variability and long-term changes of these species in the background air.
