New Present Weather Sensor

A new sensor known as the 'Parsivel®' (PARticle SIze and VELocity) is being launched by OTT Hydrometry, a world leading manufacturer of hydrometric and meteorological instrumentation.

The Parsivel® is an optical disdrometer that provides a vast amount of accurate data on the type and rate of precipitation, from a light drizzle to heavy snow.
Parsivel® achieves this by measuring the effects of both solid and liquid particles passing through a laser-based ribbon of light.

Unlike traditional raingauges, the Parsivel® is extremely sensitive, measuring down to 0.005 mm/hour and is able to maintain accuracy in extreme weather conditions. The unit has an integral heater to dissipate ice should it form on any of the measuring components.

The sensor is ideal for remote use because of its rugged, low maintenance design and simple 12v power requirement.

Data output includes particle size and velocity, rain accumulation and intensity, and present weather reports that can be processed into WMO SYNOP, METAR, and NWS codes.

Measurements are able to identify eight different categories; drizzle, mixed drizzle/rain, rain, mixed rain/snow, snow, snow grains, freezing rain and hail.

Precipitation is monitored globally by radar, however, the Parsivel® is able to provide data with which to 'calibrate' information from the radar, so that accurate predictions can be made, in flood forecasting for example.

In addition, Simon Wills, Ott's UK Managing Director, believes that the Parsivel® will be of great interest in a wide variety of other applications including road safety, military operations, aviation, outdoor sports and industrial research.
