[AAS01-P02] Global Trend of Trace Gases from 2013-2023 in Asia
キーワード：Satellite data, Remote Sensing, Atmospheric Science
In past 10 years (2013-2023), unprecedented natural hazards like Maria Hurricane, wildfires in California, Australia and Canada, earthquake and tsunami in Japan and Indonesia had significant impact in a regional scale while COVID-19 pandemic in 2020 leaves its mark on human history. In addition, the change in the trade relationship between United State (U.S.) and People’s Republic of China (PRC) since 2018 and the lockdowns during COVID-19 have caused a major shift in the global trade, especially in South and Southeast Asia. For example, wildfire caused the destruction of vegetation and infrastructure, the wildfire’s smoke plume poses huge health threat on human these pollutants from wildfire could further disrupt the Earth system when introduced. On the other hand, trade conflict between U.S. and PRC caused the relocation of factories from East Asia to Southeast Asia and the shifting of maritime trade had major impact on global shipping route. These natural and socioeconomic issues could have short-term and long-term impacts on both human and the Earth system. Here, I focus on the environmental impact on different subregions within Asia. I will investigate the global trend of anthropogenic related trace gases, such as carbon dioxide, nitrous oxide, and carbon monoxide, from 2013 to 2023 using satellite observations, such as those acquired by Tropospheric Monitoring Instrument (TROPOMI), Ozone Monitoring Instrument (OMI), Global Ozone Monitoring Experiment-2 (GOME-2), and Copernicus Sentinel-5 Precursor (Sentinel-5P). I will examine the trends of these trace gases over South, East and Southeast Asia in the past 10 years and correlate them with the socioeconomic shifts.
