where z is the extreme value and μ, σ and ξ are the three parameters of the GEV model G(z),
defining location, scale and shape parameters, respectively. This three-parameter distribution
unites the three possible extreme value distributions, namely type I (Gumbel), type II (Fréchet),
and type III (Weibull

and our intention is to run these models dur-
ing times of hazardous events and even on a daily
basis to further improve monitoring.
Avalanche monitoring has progressed. The em-
phasis is now on improving our services, especially
to the Icelandic Road and Coastal Administration
with regard to transport. The reason is that com-
munity structure has changed considerably in recent
years and the need

level in Skeidará waned. The last sign of a
crater explosion was seen at GRF early on 6
November, leaving only a weak tremor signal
from the remnants of the jökulhlaup. The
jökulhlaup fi nally ended in early December,
after ~0.8 km3 of water had drained from the
Grímsvötn lake (J. Hardardóttir, personal com-
munication, 2005).

in an overall
cold bias, compared with station measurements. To test, whether this is due to the HARMONIE
model core or the external surface scheme, biases of 2-m temperature from SURFEX are com-
pared with biases of temperature projected from the lowest two model levels to 2 mAGL. It is
found that the negative temperature biases are due to shallow inversion layers near the ground,
which are introduced

improving
management policies and practices by learning from the
outcomes of implemented management strategies. Partici-
patory integrated assessment is here a form of problem
structuring for identification of gaps, ambiguity and
multiple frames, confrontation, and integration of the
most divergent views with respect to a given problem
situation.

Future improvements should be made in the light of applications within a larger toolbox of scenario
methods.
