see the lidar data
seems that the ash is falling 1000m in about 2 hours
similar data from other MetOffice dust observation stations.
So:
(1) MetOffice, as expected, has some real time ash presence knowledge and technology in place
(2) ash is slowly falling down, as expected
, but new is flowing in so there are no clear flight levels for any prolonged time
(3) any one happy with some additives to his air intake pls see what could be expected
anyone interested pls see
