OTT Parsivel 2 at Ny-Ålesund

Mentor:S. Schnitt

Principle

The OTT Parsivel 2 is a laser-based optical system for complete and reliable measurement of all types of precipitation. The size range of measurable liquid precipitation particles is from 0.2 … 8 mm. For solid precipitation particles the size range is from 0.2 … 25 mm. The size range is divided into 32 classes. The measuring range of particle velocity is from 0.2 … 20 m/s and also divided into 32 classes. The precipitation particles are categorized as follows:

  • Drizzle
  • Drizzle with rain
  • Rain
  • Rain, drizzle with snow
  • Snow
  • Snow grains
  • Freezing rain
  • Hail
