+//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
+===== Data availability =====
+Data are available on request, please fill the {{ :joyce_data_request_form.pdf |data request sheet}} and send it to [[mailto:info@joyce.cloud|info@joyce.cloud]].
