The PWS100 determines precipitation and visibility parameters for road, marine, and airport automated weather stations. Using a novel optical system and a laser-based light source, a structured detection volume is formed. This volume allows the PWS100 to accurately determine the velocity and size of falling precipitation. The use of two separate detectors and laser Doppler anemometry techniques improve upon current present weather sensors and optical distrometers, and enables the PWS100 to accurately determine individual particle velocity and size to within ±5 percent.
