All sampling systems should be checked for bias, because systematic errors may be introduced. These systematic errors generally are caused by a loss or gain in the mass of increments during collection or by cyclical variations of coal quality at time intervals coinciding with systematic sampling time.

The incoming photons from sunlight are measured as a function of their wavelength 1 (in micrometers, abbreviated μm); the longer the wavelength, the redder is the light and the lower its energy. The ordinate is in watts/cm 2 per micrometer. To get the total solar insolation amount of incoming sunlight we must integrate for the area under the curve. In practice, we need to integrate only over ...
