It is.

Microclimate is at a scale of a few meters and less. Varations row to
row, and within the canopy - again according to the Oxford Companion.
I am not really sure how well accepted these definitions are, so I am
not particularly arguing for them. But that is why I was preferring
mesoclimate to microclimate.
