Integrated Chemistry of Ozone in the Atmosphere

​

Ozone is an important air pollutant, harmful to human health, vegetation (crop yields) and materials, and a greenhouse gas.  In the lower atmosphere (troposphere), ozone is a problem; in the upper atmosphere (stratosphere), it shields us from harmful UV light.

​

Ozone levels are hard to predict as ozone is formed in the atmosphere, by chemical reactions - it is not emitted.  We are developing new methods to measure the rate of local chemical ozone formation and removal, to distinguish between processing of local emissions, and advection.

​

The instrument development work is supported by NERC, and the project is a collaboration with the Universities of Leeds, Leicester, York and UEA (including use of the Weybourne Observatory, pictured).
