Installation and set-up of aerodynamic gauges and a laser disdrometer at the Vigna di Valle field site.
Interaction with the manufacturers is one of the main activities of the Lead Centre. The aim is to support the continuous improvement of rainfall intensity gauges, and transfer the know-how and results of the ongoing research into operational measurements. Various manufacturers of rainfall intensity gauges therefore actively collaborate with the Lead Centre. Below is a list of the related activities.
LC-PRIN is providing support to EML in assessing the performance of their aerodynamic rain gauges under various numerically simulated wind conditions. EML is also kindly providing three different rain gauge instruments for testing purposes at the Vigna di Valle field test site. Finally, the LC-PRIN will help realising a laboratory calibration rig for internal use at EML. Hosting of students at EML from the University of Genoa is envisaged to support international development of their laurea degree thesis work.
LC-PRIN is providing support to LSI Lastem in order to develop a high accuracy tipping-bucket rain gauge, suitable to the highest class of the Italian standard (UNI 11452-2012), and the associated raw data interpretation algorithms. Extensive laboratory testing of the prototype new gauge are envisaged, as well as the derivation of the optimal calibration parameters. The LC-PRIN will help realising a laboratory calibration rig for internal use at Lastem.
LC-PRIN is providing support to Lambrecht in testing their newly developed rain[e] gauge, combining the tipping-bucket principle with a weighing mechanism. Lambrecht kindly provided one rain[e] gauge for testing purposes at the Vigna di Valle field test site
LC-PRIN provided support to Geonor by assessing the dynamic response and performance of their weighing gauge within the WMO SPICE initiative. Geonor kindly provided one weighing rain gauges for testing purposes first in the laboratory and then at the Vigna di Valle field test site.
LC-PRIN provided support to OTT by assessing the dynamic response and performance of their weighing gauge Pluvio2 within the WMO SPICE initiative. OTT kindly provided two weighing rain gauge for testing purposes first in the laboratory and then at the Vigna di Valle field test site.
LC-PRIN provided support to CAE by assessing the performance of their tipping-bucket rain gauge under low intensity rainfall conditions. Various laboratory tests were performed to retrieve calibration parameters to be included in the on-board correction software. CAE kindly provided one tipping-bucket rain gauge for testing purposes at the Vigna di Valle field test site. The LC-PRIN helped realising a laboratory calibration rig for internal use at CAE.
LC-PRIN provides support to ETG for the laboratory design and fine-tuning (volumetric calibration) of their rain gauge field calibrator. Extensive tests were performed in the laboratory of the University of Genova on their tipping-bucket rain gauge, before the LC-PRIN was launched in 2010.
