Rain Gauges: Are They Really Ground Truth?

Running Head: Rain Gauge Accuracy Name Lecturer University Date The rain gauge: Are they really Ground truth? Rain gauges have been used to measure precipitation for a long time. The measurement of the gauges has been mostly taken as the truth but is that really the case? According to Nolan the accuracy of the rain gauge is greatly compromised by many factors (2001). For example, the mode of taking measurement with a rain gauge determines to a large extent the accuracy. Manual measurement are often more accurate than the automated ones. Since the measurement taken by the gauge is dependent on the c catch of the gauge anything that affects the catch ability would definitely compromise the accuracy. When the gauge catches the drops well, it is more accurate. However the size of opening of th...
