The present study addresses the aerodynamic response of the recently developed "Hotplate" precipitation gauge when exposed to the wind. The Hotplate gauge employs two heated plates to provide a reliable method of precipitation measurement. The measuring principle is based on an algorithm to associate the latent heat needed to evaporate the...

The last WMO Field Intercomparison on Precipitation Intensity highlights that non-catching type rain gauges show limited performance, in terms of precision and accuracy of the measurements, when compared to the traditional catching type rain gauges. Moreover, the performance of these instruments differ significantly from each other, this fact...

Optical disdrometers are among the non-catching type instruments used to measure liquid and solid precipitation. The increasing use of such instruments in operational observations is due to their capability to provide additional information than the precipitation rate alone, like e.g. the particle size distribution and the fall velocity of...

This study reports the results of laboratory tests performed to assess the performance of two drop counting rain gauges of the catching type, and to propose suitable correction to make them compliant with the specifications of the World Meteorological Organization (WMO) at one-minute time resolution for Rainfall Intensity (RI) measurements. The...

This chapter describes the measuring principles and technological solutions available for in-situ measurements of liquid (rain) and solid (snow) atmospheric precipitation. They can be classified into catching and non-catching precipitation gauges. Instruments belonging to the first family are generally based on gravity-related measuring...
