equation has been calibrated and verified against observations of
Class A pan evaporation values (Vehviläinen and Huttunen,
1997). The actual evaporation is calculated from potential evapora-
tion and the soil moisture deficit. The changes in temperature and
precipitation affect

no glow was seen in a flight 27 Feb.
Volcanic gas can still get dispersed all over the country, see a note from meteorologist on duty; emission of gases has not ended, neither from the inactive vents nor the extensive lava field. See how toxic values may actually get higher.
The lava field is 85 km². Its average thickness is 10 - 14 m (max 40 m) and its volume is 1.4 km³. The maximum subsidence

The last aerial acquisition over the area was performed on the 26th of June and revealed an averaged steady flux at about 13 m3/s and a total erupted volume of about 80 million m3. The last DOAS traverse, performed on the 28th of June, showed a flux of SO2 between 50 and 85 kg/s
