Abstract

In atmospheric measurements, the sampling operation is often a major source of error. This error may be reduced by consideration of the distribution pattern of the substance being measured, and the statistical principles of that pattern. From this information, guidelines as to the number, size, and location of the samples can be formulated. These guidelines should be tempered, however, with judgment and experience.
