Local Random Errors in Tipping-Bucket Rain Gauge Measurements

Evaluation of Tipping Bucket Rain Gauge Performance and Data Quality

On-line detection of errors in tipping-bucket raingauges

Tipping-bucket raingauges can produce misleading reports as a consequence of a number of factors. Very fast tips may result from gauge disturbance, faulty bucket positioning or abrupt snow melt. Very slow tips may result from partial blockage. An absence of tips is an indication of a major problem. This paper suggests easily programmable diagnostic checks that may be used to identify any of the...

Effect of the Resolution of Tipping-Bucket Rain Gauge and Calculation Method on Rainfall Intensities in an Andean Mountain Gradient

A laser-optical disdrometer served as reference to assess the absolute percent bias of calculated rainfall intensity using the data of different-resolution tipping-bucket rain gauges classically applied by climatologists and hydrologists in the Andean region. Additionally, the impact of the calculation method (tip counting versus cubic spline interpolation) was examined. The combined effect was...

Correction of Electronic Record for Weighing Bucket Precipitation Gauge Measurements

[1] Electronic sensors generate valuable streams of forcing and validation data for hydrologic models but are often subject to noise which must be removed as part of model input and testing database development. We developed an automated precipitation correction program (APCP) for weighing bucket precipitation gauge records, which are subject to several types of mechanical and electronic noise ...

On the Quality of Tipping-bucket

The WMO Laboratory Intercomparison of Rainfall Intensity (RI) Gauges described in a companion paper was the very first attempt at understanding the performances of various types of rainfall intensity gauges in controlled laboratory conditions, and provided quantitative information regarding various errors associated with RI measurements. The conclusions report that all instruments analyzed were...
