MEASUREMENT UNCERTAINTY

Specialty Definition: MEASUREMENT UNCERTAINTY

DomainDefinition

Solar

The bounds that should be placed on a measured value because of uncertainties in the measurement. If there are several factors pertaining to the measurement, such as voltage bias and temperature bias and precision of measurement scale, the total measurement uncertainty can be difficult to calculate and may be larger than the largest individual uncertainty of any one factor depending on the sensitivity of the measurement to the significant factors. There is no such thing as a perfect measurement , although some measurements are so precise that errors are negligible. Solar irradiance measurements are notoriously unreliable with the best methods (1% to 3% uncertainty, which means that an "excellent" method can produce results that may differ as much as 50 W/m2), and can become worthless (10% to 30% uncertainty) with careless methods.
