The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes. The raw data are used to calculate the type, amount, intensity and kinetic energy of the precipitation, the visibility in the precipitation, and the equivalent radar reflectivity

Applications:

  • Meteorology Observations
  • Meteorology Research

Benefits

Direct and simultaneous physical measuring principle of hydrometeors

The Parsivel² captures both the size and speed of falling particles by applied laser extinction method.

Classification of each single hydrometeors

Classification into one of 32 separate size and velocity classes and particles distribution in numbers.

Precise particles size measurements and uncertainty of rain intensity with +-5% according WMO guide line

Distinction of type of present weather and calculation of the type, amount, intensity and kinetic energy of the precipitation, the visibility in the precipitation, and the equivalent radar reflectivity.

Life time calibration and drift free measurement

Automatic compensation of temperature induced error and laser fluctuation emittance.

Unattended and maintenance free

Automatic compensation of contamination on optics by dust and aerosal layers.

Radiometric measuring principle at non-precipitation conditions
