Study of ozone and aerosol and their influence on climate and UV radiation

• Extend the high quality data set of the vertical distribution of ozone and ozone columns which started in 1969 and UV spectral irradiation measurements which started in 1989.
• Extract the additional information on aerosol available in the ozone and UV observations from the ground with spectrophotometers and from space using satellite images.
• Maintain and improve/update of the UV index prediction system.
• Inform the public about the state of the ozone layer and the UV radiation.
• Exploitation of the data:
  • use of ozone profile data in the study of tropospheric ozone events
  • use of aerosol information to investigate the effect of aerosol on the UV radiation reaching the ground;
  • effect of the aerosol properties on the accuracy of broadband UV observations
  • study of the interactions between changes in aerosol and ozone content of the atmosphere and climate changes
  • study of the ozone budget over mid-latitudes.
