The depletion of the ozone layer, first identified above the Antarctic regions and later above mid-latitudes, led in 1987 to the ratification on of the Montreal Protocol that has imposed, for a decade, drastic limitations on the production of man- man-made halogenated ozone destroying substances. As the stratospheric halogen loading is going to reach a maximum maximum in the next few years, the challenge for atmospheric scientists is to reach the level of understanding that will enable reliable prediction of the future evolution/recovery of ozone. In this perspective, it is essential to develop and maintain means for accurate long-term monitoring of the stratosphere. The aim of QUIL is to optimise the exploitation of the existing European UV-visible monitoring systems by which O3 and the related free NO2, BrO and OCIO can be measured from the ground, balloons and satellites. QUILT will provide an assessment of /the chemical ozone-loss over the last decade and through 2000-2003. This will be achieved through joint efforts in analysis improvements, consolidation of existing data series, and the near-real time integration with state-of-the-art chemical transport models.
