Microscale meteorology or micrometeorology is the study of short-lived atmospheric phenomena smaller than mesoscale, about 1 kilometre (0.6 mi) or less.
[1][2] These two branches of meteorology are sometimes grouped together as "mesoscale and microscale meteorology" (MMM) and together study all phenomena smaller than synoptic scale; that is they study features generally too small to be depicted on a standard weather map.
[3] Microscale meteorology controls the most important mixing and dilution processes in the atmosphere.
[4] Important topics in microscale meteorology include heat transfer and gas exchange between soil, vegetation, and/or surface water and the atmosphere caused by near-ground turbulence.
A micronet is an atmospheric and/or environmental observation network, composed of automated weather stations, used to monitor microscale phenomena.
