Characterization, sources and reactivity of volatile organic compounds (VOCs) in Seoul and surrounding regions during KORUS-AQ

Publikováno v: Elementa: Science of the Anthropocene, Vol 8, Iss 1 (2020)

The Korea-United States Air Quality Study (KORUS-AQ) took place in spring 2016 to better understand air pollution in Korea. In support of KORUS-AQ, 2554 whole air samples (WAS) were collected aboard the NASA DC-8 research aircraft and analyzed for 82

Observation-based modeling of ozone chemistry in the Seoul metropolitan area during the Korea-United States Air Quality Study (KORUS-AQ)

Publikováno v: Elementa: Science of the Anthropocene, Vol 8, Iss 1 (2020)

The Seoul Metropolitan Area (SMA) has a population of 24 million and frequently experiences unhealthy levels of ozone (O3). In this work, measurements taken during the Korea-United States Air Quality Study (KORUS-AQ, 2016) are used to explore regiona

Autor: David A. Peterson, Edward J. Hyer, Sang-Ok Han, James H. Crawford, Rokjin J. Park, Robert Holz, Ralph E. Kuehn, Edwin Eloranta, Christoph Knote, Carolyn E. Jordan, Barry L. Lefer

Publikováno v: Elementa: Science of the Anthropocene, Vol 7, Iss 1 (2019)

In an environment with many local, remote, persistent, and episodic sources of pollution, meteorology is the primary factor that drives periods of unhealthy air quality and reduced visibility. The 2016 Korea-United States Air Quality (KORUS-AQ) field
