Some of these stations are difficult to get back online without site visits. Consequently they
may therefore be out-of-service for extended periods. Based on an estimate of the
completeness of the GPS data-set in 2010, the uptime of the network is about 70.5%. For

from wind energy in the Nordic countries and how they might change due to global warming during the next decades. This relates both to the production potential and especially design conditions for wind farms and their sensitivity to climate change. The principal aims of the wind energy group is to analyse extreme wind in the Nordic countries in the form of an extreme wind atlas (50-year wind

dissemination of macroseismic questionnaires and the authors, i.e. people who wrote down earthquake
observations. Eight generations of Finnish macroseismic questionnaires since 1882 are discerned. The
ownerships belonged to one geologist, the Geological Commission, the Geographical Society

for melt (Qm) is calculated as follows:
Qm = (1 − α)Sin + C0 + C1Ta (2)
Where α is the albedo for the surface (three fixed albedo values are applied: snow = 0.8, firn
= 0.55 and ice = 0.42), Ta is in ◦C and C0 +C1Ta is the sum of the longwave radiation balance
and the turbulent exchange (Oerlemans, 2001). C1 is set to 10 Wm−2 K−1 (Oerlemans, 2001)
and C0 is tuned to −45 Wm−2 K−1. Accumulation equals
