Performance of post-processing algorithms for rainfall intensity using measurements from tipping-bucket rain gauges

Evaluation of Tipping Bucket Rain Gauge Performance and Data Quality

Improved Micro Rain Radar Rainfall Measurements using Doppler Spectra Post-Processing

The Micro Rain Radar 2 (MRR) is a cost effective, minimum maintenance oriented, portable radar system used for conducting precipitation research. This system is prone to several draw backs such as lack of a sophisticated post-processing algorithm to improve its sensitivity, noise due to radar receiver and the lack of high quality Doppler radar moments. In this project work, we propose an improv...

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...

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...

Certified accuracy of rainfall data as a standard requirement in scientific investigations

This paper elaborates on the rationale behind the proposed standard limits for the accuracy of rainfall intensity measurements obtained from tipping-bucket and other types of rain gauges. Indeed, based on experimental results obtained in the course of international instrument Intercomparison initiatives and specific laboratory tests, it is shown here that the accuracy of operational rain gauges...
