First idea: Minimized Particle Analyzer (MiniPA)Based on MiniLDA, tophat-profile, intensity analysis

Measuring Volume = 0.1mm3

Measuring Frequency = 100kHzParticles: Drops and ice crystals

Information about:• Particle size• Particle velocity (2D)• Turbulence

Second idea: Cloud Particle Sensor (CloudSens)Based on enlarged NebioSens

Measuring Volume = 100 – 1000cm3

Measuring Frequency = 10kHzParticles: Drops and ice crystals

Information about:• Particle type• Particle concentration
