ICE - Laboratory experiment goals
• Basic scientific understanding• Check performance of airborne instruments• Develop new measurement techniques & combining
methods (CVI -> CFDC)
STRENGTHS:
Environment control
Repeatability
Mechanistic studies
Test specific aerosol types (dust, bacteria, ..)
Crystal growth habits & rates
Effects of organic coatings, electric charge, ..
Laboratory Experiments A. Cloud types
Layer• upslope
• stratus
Wave
Cumulus• warm base
• cold base
