The history of instrument intercomparisons in the case of rainfall measurements dates back significantly in the last centuries. Symons realized the first intercomparison of rain gauge instruments at Hawskers - Yorkshire, UK in 1858 (from Stow, 1871 as reported by Goodison et al., 1998), whose experiments in the field are depicted below. However, most international rain gauges intercomparison efforts focused on accumulated amounts of precipitation, low intensity rainfall (snow) and sometimes only on qualitative RI information (light, moderate, and heavy).
The latest WMO international intercomparison effort had the objective to assess and compare counting and catching errors of both catching and non-catching type of rain intensity gauges.
