OTT Pluvio 2 L at Ny-Ålesund

Mentor: S. Schnitt

Measurement principle

The OTT Pluvio 2 L is a precipitation gauge basing on a weighing measurement principle. It detects both liquid and solid precipitation by weighing the bucket content. The following values are recorded:

  • intensity
  • accumulated intensity
  • bucket filling level
  • temperature load cell

The instrument is equipped with a orifice rim heater to prevent accumulation of snow and ice on the orifice rim.


Current setup of OTT Pluvio 2 L at AWIPEV Ny-Ålesund, Svalbard, next to the atmospheric observatory.
