Nya mätningar av vulkanaska

[Marielou]

Nya observationer av vulkanisk aska från Met Office:
"Met Office scientists have been working with the Universities of Reading and Hertfordshire to gather comprehensive data about the potential danger to aircraft from the volcanic plume.
The volcanic dust was measured using newly-developed probes that attach to meteorological balloons that can be used for measuring volcanic dust. The weather balloon and probe was launched at 9 a.m. on Monday morning and clearly showed a 600 metre-thick layer of dust at a height of 4 km.
The layer was found to contain highly abrasive dust particles, at concentrations of a third of a milligram of dust in each cubic metre. While the amount sounds small, a typical jet engine would ingest some 60 billion of these particles every second."
Vågar vi verkligen flyga nu? betänk att det är de stora flygbolagen som pressat fram ett beslut att öppna upp luftrummen i stora delar av Europa. Trots protester från myndigheter och mätobservatörer.
