SID-3
Small Ice Detector 3

The Small Ice Detector 3 (SID-3) is an in situ airborne particle imager built by the University of Hertfordshire. It measures high-resolution angular scattering patterns of individual cloud particles to determine particle size distribution and number concentration. It operates at 532 nm and has a 5 to 50 μm detection range. SID-3 provides number concentration measurements typically every 1 second and particle size distribution measurements every 10 seconds.
