Mesoclimatology
From Glossary of Meteorology
mesoclimatology
The study of mesoclimates; the climatology of relatively small areas that may not be climatically representative of the general region.
The data used in mesoclimatology are mostly standard observations. The size of the area involved is rather indefinite and may include topographic or landscape features from a few acres to a few square miles, such as a small valley, a forest clearing, a beach, or a village site.
