The climate modelling community needs reliable estimates of the stratospheric aspects of climate forcing, and of their variation over time, for use in scientific assessments of climate change by the IPCC. A SPARC working group has been established to review and consolidate the available estimates of observed variations of the ozone distribution, stratospheric volcanic aerosols and solar radiation. These will be used to generate best estimates of the time variations over the last 100 years of the solar constant and the distributions of ozone and stratospheric aerosols.
The working group co-ordinates closely with other international activities, such as those linked to the WCRP Working Group on Coupled Modelling, which are developing related data sets on time variations of greenhouse gas concentrations and of distributions of tropospheric aerosols.
