OTT Pluvio 2
Mentor: S. Schnitt
Principle
The OTT Pluvio 2 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
Instrument
Current setup at Research Center Jülich on the roof of IEK-8: Pluvio 2 .
