The MET office, like every other meteorological institute has access to data that can provide the ash density with an accuracy of around +-30%. The ash extent/movement can be mapped to within 6km at worst and 500m at best.
I was, however, unaware that the MET office was supposed to predict the effects of ash upon aircraft.
Simonpro,
As you are well aware, no one has suggested that the MET office should provide predictions as to the effects of ash on aircraft. indeed, we are well aware of what the effects are and how those effects occur in large concentration.
if the MET office can provide ash density figures with an accuracy of +/-30% from 6km to 500m over specific airways and and specific levels, why has that not been done and the information disseminated to NATS in order that ASHTAM's can be issued and airways and flight levels opened to IFR traffic?
toodle back to the Global Warming Thread and continue to praise Jones and the CRU for manipulating climate change data.
