where c is the speed of light (c = 2.99 x 108 m/s). In principle, CL51 is able to detect three cloud
layers simultaneously, but if the cloud base is obscured due to precipitation or ground-based
fog, vertical visibility is reported. Information about fog and precipitation can also be derived
from the return signal as they attenuate the return signal from a cloud. In its

The hydraulic conduc-
tivity of the sand formations is generally high, of the order
of 104–103 m/s [Harrar et al., 2003; Sonnenborg et al.,
2003]. In general, groundwater flows from east to west. At
the water divide to the east the hydraulic head level is about
75 masl, decreasing to sea level at the west coast. The
average head gradient is 0.001. The seasonal variation in
head values is generally less

can reach up to 10 m s 1 at various locations around the Icelandic coast (Einarsson, 1976). Land

breezes occur less frequently and are generally weaker. On intermediate time-scales of several
days, temporal variability is primarily due to the evolution and passage of cyclonic storm systems.

an event. Reasons for this lack of confidence might include
a judgement of the information as incomplete, blurred, inaccu-
rate, unreliable, inconclusive, or potentially false. Similarly,
a person is certain if s/he

Weather forecast for the next 26 hours:
Today (Wednesday): East winds, 20 to 28 m/s with snow in the south and west part of Iceland, but later sleet and rain by the coast. East 18 to 28 m/s in the afternoon, strongest winds by the coast

Wind speeds measuring 20 m/s and higher were recorded at half of the automatic weather stations in the lowland areas and similar speeds were recorded at 80% of automatic weather stations in the highland areas.
In the town of Heimaey in the Westman Islands, wind-speed* of 28 m/s and gusts measuring 45.8 m/s were recorded at the height of the storm, setting

Energianalys will forecast energy system variables, while SINTEF Energy Research will make
assumptions for the energy system in different cases, include new inputs in the EMPS model and
carry out simulations.
