Directory entires that have specified Fennoscandia as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

Objectives 1. To develop the measurement technique further, providing more accurate measurements and extend the method to a larger number of trace species 2. To monitor the presence of CFC:s and other longlived anthropogenic tracers in the stratosphere 3. To use long-lived anthropogenic species as tracers of atmospheric motion, in particular for comparison with atmospheric models Reserarchers: Descartes is a joint research programme currently involving N.R.P Harris and J.A. Pyle, Centre for Atmospheric Science at the Department of Chemistry, University of Cambridge, U.K., and Hans Nilsson and Johan Arvelius, Swedish Institute of Space Physics, Kiruna, Sweden
Objective: to determine how solar activity influences temperatures, winds, electric currents and minor constituents and to allow possible anthropogenic influences to be determined. Uses primarily measurements by the ESRAD and EISCAT radars, plus ground-based and balloon-borne measurements of atmospheric electric fields and currents.
It has become clear in recent years that a changing composition of the atmosphere due to human activities may influence the climate system. The production of greenhouse gases and their accumulation in the atmosphere can result in a global warming and changes in the climate system. On regional scales, this may result in even much more pronounced changes. This is particularly true for the high northern latitudes. Climate changes will impact the society and nature in many ways. The anticipated effects are large and will matter both globally (mainly negative consequences) and regionally (both negative and positive consequences). SWECLIM provides users with detailed regional climate study results. SWECLIM develops regional (limited area) climate system modeling, studies climate processes and feedback special for the Nordic region and creates regional climate (change) scenarios on a time scale of 50-100 years. SWECLIM also performs impact studies on water resources. Climate scenarios are also made available for other impact studies, such as in forestry, done by external groups. Information activities on climate change and the regional consequences are an important component in the program. The regional climate model system is built around a regional atmospheric model, regional ocean models with sea ice for the Baltic Sea and land surface modeling plus hydrology. The model system is forced at the by large-scale results from global climate models. Multi-year to multi-decade length integrations are performed with the regional model targeting a domain roughly centered on the Nordic countries and using horizontal resolutions ranging from 20-80 km.
