If a substantial amount of money is being spent in establishing a network, it is desirable to increase the budget slightly in order to include a few additional stations or kinds of measurement. As the investigation proceeds, it is sometimes found that the original objective requires modification, that some secondary or unforeseen question becomes more interesting than the primary one, or that the data prove to be of interest to scientists in other parts of the world or perhaps in other disciplines.

A classification of scales of motion is arbitrary and depends on individual preference or convenience. Nevertheless, Table VII may be a helpful qualitative summary. The Rossby number Ro has been used as one criterion. 1) Ro = V/fL where V and L are characteristic velocities and lengths, and / is the Coriolis parameter, derived for each latitude from the component of the earth's rotation in the direction of the local vertical. On the microscale, / and Ro become irrelevant. 2. MICROMETEOROLOGY Micrometeorological models and methods are closely linked to those in fluid mechanics.
