Principle of operation

Measured parameter Ice or droplet shape
Operating principle

- Measurement of mixed ice-water phase cloud microphysical properties:
- Ice crystal size distribution and concentration
- Ice crystal shape and habit/Ice water content
- Supercooled droplet and Freezing drizzle drop measurement/identification
- 1 million pixel CCD camera with 2.3µm size resolution provides images of particles up to 2mm in size. Up to 40 frames s-1 with up to 100 particles per frame. Sample volume 1 l/sec at 200 m s-1.
- Individual particle images are identified, sized, cropped and stored in real time.
