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).

a systematic com-
parison of results to observed precipitation has been carried out. Un-
dercatchment of solid precipitation is dealt with by looking only at
days when precipitation is presumably liquid or by considering the
occurrence and non-occurrence of precipitation. Away from non-
resolved orography, the long term means (months, years) of observed
and simulated precipitation are often

and possibly the stake-
holders at different phases of the modelling project.
Many QA guidelines exist such as Middlemis (2000) and
Van Waveren et al. (1999). The HarmoniQuA project (Schol-
ten et al., 2007; Refsgaard et al., 2005a) has developed a com-
prehensive set of QA guidelines for multiple modelling
domains combined with a supporting software tool, MoST

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.

the principalmethods have not changed much over the years, theamount of field work has varied. In the first 15 yearsthe monitoring programme at Storbreen was com-prehensive, often three or more snow density pits
were dug, snow depth was measured at about 600points and ablation was measured on 30 stakes
evenly distri uted on the glacier (Liestøl 1967).Based on experience of the snow pattern, the ob-
