SHIVA - Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere


University of Cambridge, United Kingdom (UCAM)


The Centre for Atmospheric Sciences (a collaboration between the Departments of Chemistry, Geography, and Applied Mathematics and Theoretical Physics) at UCAM has a broad programme in atmospheric sciences, covering field and laboratory measurements, modelling, and theoretical geophysical fluid dynamics. UCAM has provided outstanding contributions to problems of atmospheric dynamics and chemistry, with a focus on the upper troposphere/lower stratosphere.

UCAM has played a leading role in European stratospheric ozone research since the late 1980s when it first hosted the European Ozone Research Coordinating Unit (EORCU). We have organised and coordinated many successful European field campaigns (EASOE, SESAME, THESEO) and currently coordinate the 65- partner IP SCOUT-O3. UCAM is also a major contributor to the UK National Centre for Atmospheric Science. In particular, UCAM scientists are playing a lead role in developing, jointly with the Met Office, a new chemistry-climate model, UKCA.

Tasks within SHIVA:

  • Coordination of work package 6
  • UCAM will provide modelling results based on CTMs and coupled CCMs (WP-4, WP-6).
  • The models will be used to assess the impact of VSLS on stratospheric ozone, and to analyse how changes in trop-strat exchange in a future climate may affect the transport of VSLS into the stratosphere, and hence its impact on stratospheric ozone (WP-6).
  • UCAM will provide model calculations of VSLS transport into the stratosphere using trajectories and simplified chemical and cloud microphysical schemes in order to better quantify uncertainties in VSLS transport into the stratosphere (WP-4).
