Quadrennial Ozone Symposium 2021
October 3 (Sunday) - 9 (Saturday), 2021

WELCOME MESSAGE

I am very pleased to invite you to attend the Quadrennial Ozone Symposium (QOS) in South
Korea, on 3 - 9 October, 2021. Despite its tiny fraction, ozone is a crucial gas in the Earth
Atmosphere. The ozone layer in the stratosphere protects life on Earth by filtering out damaging
ultraviolet radiation from the sun. In the troposphere, ozone is an important greenhouse gas
and a strong pollutant at ground level. Since the last QOS that took place in Edinburgh in
2016, a variety of new developments have taken place on all facets of atmospheric ozone,including its observation and impact on human health and ecosystems. The Symposium’s
program addresses all these aspects. Through the foreseen keynote talks, presentations at thesessions and discussions at poster sessions and side events, QOS 2021 is of high interest for
all scientists throughout the world interested in atmospheric ozone and more generally in thestudy of the Earth’s atmosphere.

Seoul is a mega-city with advanced modern technologies, and has a long history as the capital of Korea since 1394.
The first ozone layer observation in Korea was done by Prof. Emeritus Hi-Ku Cho with the Dobson spectrophotometer in1984 at the Department of Atmospheric Sciences, Yonsei University. Since then, ozone observation has been continued
with the addition of Brewer Spectrophotometers, and Pandora instruments throughout the country. Surface ozone
concentration has been also measured by the Ministry of Environment since 1989. These missions are to be followed by
the launch of Geostationary Environment Monitoring Spectrometer (GEMS) in early 2020. We, LOC members would liketo extend a warm and hearty welcome to you all. Hope you enjoy the symposium.
