Current research

How well do we understand the atmospheric effects of climate change and their impact on O3
(H2O, T, circuln, clouds,ppn)?
– How robust is the water vapour increase?


Which natural emission changes can we realistically model? (lightning, biomass burning,
vegetation)

Is atmospheric variability (El Niño,…) an analogy for climate change?

Should we be trying to decrease or increase the uncertainty in the ozone forcing predictions?

Future plans

How useful is the strat-trop separation - should we be moving to whole atmosphere models?

Are the SRES emission scenarios adequate for ozone modelling?

How important is it to model the past correctly (1860’s or 1960’s)?
– Are the emissions, stratospheric ozone good enough?


Model/measurement intercomparisons: should we intercompare processes/budgets rather than
concentrations?

What are we missing?
