Objective
In the European Arctic there are two research stations, which are part of the global Network for the Detection of Stratospheric Change (NDSC), namely Thule (Greenland: 76°N, 69°W), operated by Denmark and Italy, and Ny-Ålesund (Spitsbergen: 79°N, 12°E), operated by Germany and Norway. The objective of this project is to perform the full measurement programme required for NDSC stations and to improve the data analysis and interpretation in the field of stratospheric chemistry and ozone depletion. The measurements allow the description, the chemical composition and the dynamics of the Arctic stratosphere. Data will be provided about the ozone concentration profile, stratospheric aerosols and compounds like CIO, N2O, NOx, HCI, HNO3, CIONO2, CFCs.
The following topics are in the scope of this project:
(i) The evolution of the chemical composition of the Arctic stratosphere will be observed throughout the year, to detect any "perturbed chemistry" which initiates chemical ozone depletion.
(ii) The presence of stratospheric aerosols like Polar Stratospheric Clouds (PSCs) or volcanic aerosols from Mt. Pinatubo.
(iii) Information on the dynamics of the polar vortex will be deduced from available long-lived tracers, like volcanic aerosols or trace gases like N2O.
(iv) Special attention will be paid to exchange processes across the vortex boundary. The two stations are well located for these studies, as the vortex boundary is often found between them.
(v) The application of stratospheric models will help to analyse specific observations recorded during the project period.
Observations will be carried out all year in 1994 and 1995, in order to determine the evolution of the Arctic stratosphere before, during and after SESAME. Measurement activities will be intensified during the winter periods and especially during SESAME.
Results of measurements will be collected in a common database at NILU. A common data protocol will be agreed with the participants of the ESMOS/Alps project and the groups involved in the SESAME campaign in order to allow for a common data centre and mutual data exchange.
