How are ratings determined?
• UK network standards assume seasonal
average temperatures and worst-case
wind conditions, i.e. low wind speeds
Summer → 20˚C; Spring/Autumn → 9˚C;
Winter → 2˚C
• Real-time monitoring (‘dynamic rating’) is
not commonly

favourable, but less settled than during the previous three
years. The temperature was above the 1961-1990 normal, about 0.7 to 0.9°C in most areas,
but 0.3 to 0.6°C in the Southeast. The highest temperature of the year was measured at Burfell
in the southern inland on 23 July, 25.9°C and the lowest at Kolka in the central highlands on 2
January -23.0°C.
The precipitation was below normal

Noises: Scientists working at Gígjökull regularly hear explosions and booming
sounds and feel the ground vibrate. The vibrations are not felt in 3-4
km distance.
Additional note: The scientists at Gígjökull experienced discomfort due to gas.
Meltwater: Today water temperature at the Markarfljot bridge was measured 11°C
but about 3°C in a 2 km distance from Gígjökull. Water
