International research and collaboration
In close national and international collaboration, the DKC is monitoring and researching into ozone and UV radiation. The monitoring is supported by the Danish Ministry of the Environment, and our measurements contribute to the international Network for the Detection of Atmospheric Composition Change (NDACC).

The Arctic is one of our focus areas, and we are monitoring the restoration of the ozone layer and UV level above Greenland under climate changed atmospheric conditions, from NDACC-stations in Pituffik, Kangerlussuaq and Scoresbysund.
Monitoring data are submitted to databases under NDACC, World Ozone and UV radiation Data Center under the WMO program GAW, WMO’s GCOS and AMAP. The ozone measurements will also contribute to a possible future Danish climate surveillance program.
The SCOUT-O3 project
The five-year project SCOUT-03 was a European Commission Integrated Project that involved 59 partner institutions and over 100 scientists from 19 countries. SCOUT-O3 ran until 31 April 2009 and aimed to develop predictions about the evolution of the coupled chemistry/climate system, with emphasis on ozone change in the lower stratosphere and the associated UV and climate impact.

The central purpose of the SCOUT-O3 project was to provide scientific knowledge for global assessments on ozone depletion and climate change for the Montreal and Kyoto Protocols.
An estimation of how and when the ozone layer and UV radiation will recover, as CFC concentrations decrease, is required within the next few years, and could prove essential to European policy makers, and be used to develop the European position on sustainable development.

Long-term effects of UVR in Europe
In cooperation with several medical and health institutes in Europe, The DKC is involved in the interdisciplinary European project ICEPURE, which aims to determine the beneficial and harmful biological effects of UVR and critical dose levels in relation to personal UVR exposure. This includes studies of vitamin D synthesis, DNA damage and immunosuppression.
The role of the DKC is to combine UV measurements and satellite data and to develop a personalized UVR exposure model in order to model personal UVR exposure of small or large population groups.

Personal exposure data from wristwatch dosimeters worn by volunteers, and from diaries that participants keep of their daily behaviour, will be correlated with location matched ground station and satellite data to develop combinatorial radiative transfer and behavioural models that can be used in climate models to predict future UVR levels and assess the impact of climate change on human UVR exposure.
