Abstract

The Parsivel is an optical disdrometer that measures the velocity and size of falling hydrometeors with the goal of classifying hydrometeor type and retrieve precipitation Particle Size Distribution (PSD). We use an OTT Parsivel² laser-optical disdrometer that functions with two sensor heads facing each other. One head is a transmitter that emits radiation (at 650 nm wavelength at the red band) in a horizontal plane and the other head is a receiver that senses how much of that radiation is received. The instrument measures the size of the hydrometeor by measuring the length of radiation that is blocked by the particle diameter. The velocity of the hydrometeor is estimated based on the time that a particular hydrometeor is blocking the radiation between the transmitter and receiver. The OTT Parsivel² retrieves particle velocity and size every minute, with a range in velocity from 0.2 to 20 m/s and a range in particle diameter from 0.2 to 25 mm (OTT Hydromet GmbH, 2018).

Purpose

This data was collected to support the GWF project "Mountain Water Futures".

Plain Language Summary

This instrument measures the number, shape, and size of the raindrops and snow crystals close to the surface. These information are important to know for the understanding of precipitation dynamics, more specifically to know how much water volume each raindrop and snow crystal carry before they reach the surface.
