Spherical gauges for improving the accuracy of rainfall measurements
Compared with the pit gauge , average deficiency in catch ranged from −1% (spherical rain gauge orifice with cylinders) to 4%, whereas the deficiency for the standard gauge was −10%.
SAMPLING ACCURACY OF PIT VS. STANDARD RAIN GAGES ON THE FERNOW EXPERIMENTAL FOREST 1
Pit gages caught significantly (P=0.05) more rain than did standard gages at each of four locations tested.
EVALUATING THE ACCURACY OF RAINFALL CATCH BY THREE DIFFERENT GAGES
ABSTRACT: A U.S. standard gage, a weighing‐type recording gage, a standard gage fitted with an Alter windshield, and a pit gage were installed to evaluate the accuracy and wind effects on rainfall catch.
Experiments on the shielding of raingauges
Table VIII. gives the totals from the experimental pit gauge P and the Beckley gauge B for corresponding winter and summer periods.
Challenges in obtaining reliable measurements of point rainfall
This is why the World Meteorological Organization (WMO) recommends a pit gauge , protected against in-splash by a metal or plastic grid, as the reference standard for rain measurements [e.g., Sevruk and Hamon, 1984; Sevruk and Nesˇpor, 1998].
Field assessments on the accuracy of spherical gauges in rainfall measurements
Based on 131 storms at Nacogdoches and 94 storms at Shreveport, observed between May 1998 and February 2001, the results showed: (1) spherical gauges recorded an average 6–9% greater than standard gauge and 3–4% less than pit gauge , only 1–2% less than …
Errors and correction of precipitation measurements in China
Field intercomparison observations regarding 29,000 precipitation events have been conducted using one pit gauge , two elevated operational gauges and one horizontal gauge at the above 30 stations.
Adjustment to rainfall measurement undercatch with a tipping-bucket rain gauge using ground-level manual gauges
They seem to be less accurate, in that they tend to measure less rain than pit gauges that are installed in the ground with their orifices at the ground surface (WMO 1984; Sevruk 1996; Upton and Rahimi 2003).
Numerical models of the raingauge exposure problem, field experiments and an improved collector design
A small diameter flat champagne glass collector has been tested for over 31/2 years against a standard 5′’ cylindrical gauge, a 5′ pit gauge and an inverted conical gauge at the Institute of Hydrology, Wallingford.
Rainfall measurement revisited
A second WMO inter- comparison was carried out in the 1970s using the Wallingford-type pit gauge as the reference (WMO, 1970).
