Consolidated O3, NO2, BrO and OClO column measurements at ground-based stations

Over the past decade, in the framework of the international Network for the Detection of Stratospheric Change (NDSC), European capability to monitor stratospheric ozone and the related active radicals NO2, BrO and OClO using ground-based UV-visible spectrometry has been established. A key-aspect of the NDSC is the need to establish methods to improve and consolidate the existing long-term data sets, so these data can be safely used for trend assessment and satellite validation.

This result consists in the establishment and collection of a homogenised data set of column measurements of ozone, NO2, BrO and OClO at approximately 30 stations covering all latitudinal bands of both hemispheres. This data set is made available to the scientific community through the QUILT web site. It also provides a valuable European input to the NDSC.
