A procedure to adjust rainfall intensity (RI) measurements to account for the wind-induced measurement bias of traditional catching-type gauges is proposed and demonstrated with an application to a suitable case study. The objective is to demonstrate that adjustment curves derived from numerical simulations and disdrometer measurements allow...

Since solid precipitation records, and the associated wind speed data, are commonly stored with a quite coarse resolution in time (30 or 60 minutes), we investigated the impact of the aggregation scale on the accuracy of data corrected by using the transfer functions. We used data from the WMO SPICE (Solid Precipitation Intercomparison...

Catching-type precipitation gauges are affected by wind-induced undercatch due to the modification of the airflow around the gauge body. The wind speed-up and updraft above the gauge orifice induces variations of the particle trajectories and, in some cases, leads them out of the measuring area; this produces an underestimation in precipitation...

The airflow surrounding any precipitation gauge is deformed by the presence of the gauge body, resulting in increased flow velocity above the orifice of the instrument, which deflects the hydrometeors (liquid/solid particles) away from the collector. The main factors of influence are the gauge shape, the wind speed and the type of...
