The Arctic is a region which to high extent influences the atmospheric behaviour in the Northern hemisphere and for this reason attracts the attention of the scientific community. The Atmosphere Research Flagship Programme (http://nysmac.npolar.no/research/flagships/atmosphere.html) is an activity aimed to unite the efforts of scientists working in different fields of polar atmospheric research.
An important task of this activity is the study of solar UV radiation and ozone column that are considered important parameters for both climatic studies and biophysical examination of ecosystems. Several observational stations based in Ny-Ålesund, Hornsund and Barentsburg perform measurements of these parameters on a long-term basis.
The objective of the present proposal is to create the basis for their integration into a regional monitoring network, which will also lead to a closer cooperation of the researchers involved in these activities. Since the technical features of the current instrumentation at the stations involved are quite diverse, it is important to compare their ability to provide reliable and homogeneous data sets.
For that reason, an intercomaprison campaign planned in the frame of the proposed activities is considered an important element for the establishment of a Svalbard UV network. Another significant goal is the joint analysis of the available data and elaboration of common data format and data processing strategy for the future network that will provide a homogeneous data set. It is expected that the results achieved in the frame of the present proposal will contribute to more realistic conclusions made by the climatological and biophysical studies.
