PVM 100 Cloud Probe

PI: Dr. Eleftheriadis Konstantinos ( Operators: Dr. Fetfatzis Prodromos (

The Gerber PVM-100 measures liquid water content and effective droplet radius of ambient clouds by directing a diode-emitted laser beam along a 40-cm path. The forward scatter of the cloud droplets in the open air along the path is measured, translated and expressed as water content.
