QOS 2024

The Quadrennial Ozone Symposium Organizing Committee is pleased to announce that QOS 2024 will take place from 15–19 July 2024 in Boulder, Colorado, hosted by the University of Colorado Boulder with a hybrid virtual option.

We are excited to follow in the footsteps of a wonderful QOS 2021 graciously hosted online by Yonsei University, Korea.

The 2024 Quadrennial Ozone Symposium is the 36th meeting of Ozone Scientists that began with the “Conference on Ozone and Atmospheric Absorption” in Paris in May 1929. The previous meetings have been highlighted with our growing understanding of processes affecting atmospheric ozone, its observations, photochemistry, impacts on air quality and human health, as well as the existential threat of ozone layer depletion by chlorofluorocarbons and halons. This 36th symposium will highlight keynote and invited presentations on wildfire aerosol impacts on ozone, new findings of the Hunga eruption impact on the stratosphere, the anniversaries of the Aura satellite and IAGOS observations, increased awareness of ozone and stratospheric impacts on surface climate, and new satellite data from the Korean GEMS satellite and the NASA TEMPO instrument. Plan to submit your abstract before 1 March 2024!

LOC committee and Scientific Program Committee

The committee felt that all candidates were very deserving of the award. Its members considered multiple categories in making a final decision. In the end, the decision  was to split the Farman award between two nominees.

Herman Smit 
In recognition of his unique contribution to the calibration and quality 
of the global ozone sonde record

Philippe Nedelec 
In recognition of his contribution to produce high quality ozone record 
in the troposphere and lowermost stratosphere using in situ 
observations on-board commercial aircraft

For the Dobson award, committee selected high impact paper lead by

Luke Western 
Paper "Global increase of ozone-depleting chlorofluorocarbons from 2010 to 2020" was published in Nature Geoscience in 2023 .
