The dense network of 49 raingauges over the 135 km2 Brue catchment in Somerset, England is used to examine the accuracy of rainfall estimates obtained from raingauges and from weather radar. Methods for data quality control and classification of precipitation types are first described. A super-...
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 can be reduced to the limits of 卤1% after proper calibration and correction. This figure is...
While rain gages have long served as a trusted source of surface-level precipitation measurements7, they often fail to capture the spatial variability of rain events, especially during convective storms8,9,10. This inability to resolve spatial patterns in rainfall is made worse by the fact that...
Generally speaking for power meters, there are strain gauges involved. At the most simplistic level these gauges measure the force as torque, and then combined with cadence can determine your power (wattage). In today’s power meter world, the vast majority of units use accelerometer-driven cade...
(recent examples include Gent et al.2018; Bock and Chiang2019; Hamada et al.2019; Xu et al.2019). The percentage scale ranges from zero to 100% and a rater gauges the proportion of the organ showing symptoms and estimates the severity accordingly. The percentage scale data is amenable to...
The accuracy of the estimates of hourly rainfall derived from both calibrated and uncalibrated C-band (5.6 cm wavelength) radar located in northwest England has been assessed. The raingauge calibration procedure using five telemetering raingauges significantly improves the accuracy, as compared with ...
Daily historical raingauge data from several Canadian sources and field experiments were compared to the World Meteorological Organization (WMO) pit gauge rainfall measurements in order to determine the accuracies for different operational rain gauges. The detailed technical description of the main ...
Correction techniques for tipping-bucket rain gauges and their influence on the accuracy of rain intensity measurementsG., Lanza LA., MoliniL., StagiG., Cassini
The effects of removing each raingauge were compared with computations using all raingauges. Comparison results indicate that (1) the block Kriging method can accurately describe rainfall processes in terms of the spatiotemporal structure of a semivariogram. (2) the block Kriging method is better ...
At the storm total time scale the DSP product offers a good rainfall estimation and detection, the correlation with rain gauges is the highest (KEWX R= 0.59 and KDFX R= 0.37); the mean relative differences between gauges observations and radars estimates are the lowest (52% for the KEWX ...
