In
meteorology, a
mesonet is a network of (typically) automated
weather stations designed to observe
mesoscale meteorological phenomena.
Dry lines,
squall lines, and
sea breezes are examples of phenomena that can be observed by mesonets. Due to the space and time scales associated with mesoscale phenomena, weather stations comprising a mesonet will be spaced closer together and report more frequently than
synoptic scale observing networks, such as ASOS. The term mesonet refers to the collective group of these weather stations, and are typically owned and operated by a common entity.
