Measurement Issues (Needs editing)

• Small ice properties (< 100 μm), water/ice discrimination, Low concentrations (poor sampling statistics)

• Avoiding Shattering and Splashing• Liquid/Solid/Total Water, Ice Water Separation,

Extinction• Composition/Concentration of Ice Nuclei• Platform dependent issues (e.g., high speed, rotary

wing, unpiloted and commercial aircraft)

To be added:

New Analysis TechniquesNew and emerging measurement platformsNew integrated measurement techniques

Continuing Issues and recommendations (Needs Editing)

• Many new instruments since 2002, how can they be validated/referenced to older instruments

• Many new instruments developed at research institute – how do we make them available to broader community

• Modifications/improvements continue to be made on

existing, individual instruments – how to implement on other similar sensors?

• How can we encourage new developments by young investigators?

• Should there be stronger links between private business and research institute?
