Experiment Design
Design the experiment so that the preliminary model can be verified and/or fine-tuned for improved accuracy over a wide range of environmental conditions. Clearly define the control volume that is being used to calculate air, moisture, and energy balances. Often, a cleverly-designed experiment can take a relatively short time (no more than a week) to conduct, yet still yield the desired verification of the model. Some phenomena are, by their nature, very slow-moving, (e.g., deep-ground temperatures), and experiments that involve these types of measurements may last many months or even years.
