April 24-25 night
Raman Lidar at
22:34 UTC
LL Lidar at 01:55 UTC
is the first scan and
confirms thick low
clouds
April 25, morning
LL Lidar at 9:21 UTC
Raman Lidar at 10:05
UTC, same day
Are we sure
that these are
ashes?
April 25-26 night
No elastic data available till midnight local time
Raman data available at the beginning of the night (19:34 local)
April 25-26 night
LL Lidar at 3:47 UTC
A thin layer at 8 km is
observed, the clouds at 5 km
are not visible
Raman data in the middle of
the night (4:32 UTC) do not
see any layer.
