Ash Detection
• Pilot Reports of Ash or No Ash– Routine receipt across NZ
and between Australia and NZ.
– Reports grounding flight operations

Ceilometer and LIDAR
• CL31 – ceilometer on certain of MetService’s AWSs
• 2 CL viewing licences.– 17 locations around NZ.
• NIWA operated LIDAR, located in Lauder

Pilot Reports
• Evidence of ash and no ash in satellite imagery
• Conflicting Pilot Reports– NO ASH and ASH reports
over similar flight routes.Image Source: http://franksemails.com/pics/erj190-in-argentina/

Consistency

Possible VAG Confidence Levels
• Confidence in the position of lateral boundaries of ash cloud– High = Black–Medium = Blue– Low = Red
• Same technique could be used to assess confidence in the vertical extent

Confidence of Vertical Extent
• Objective confidence levels– IR Temp and Sounding vs
Lidar, Radar and PIREP– Amount of consistent
