Pluviometer
Pluviometer installed at Jülich
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
JOYCE-CF Standard Operation Procedures
- Temporal resolution 1 minute
- Precipitation amount
