Mesonet is a combination of the words "mesoscale" and "network".
In meteorology, "mesoscale" refers to weather events that range in size from a few miles to a few hundred miles. Mesoscale events last from several minutes to several hours. Thunderstorms and squall lines are two examples of mesoscale events.
A "network" is an interconnected system.
Thus, the Weather Underground Mesonet is a system designed to measure the environment at the size and duration of mesoscale weather events.
Your weather station is an important tool for meteorologists and hobbyists to predict local weather conditions. It is important you maintain your weather station, including proper installation and calibration.
Virtual Weather Station allows you perform an ?end-to-end calibration? by applying a gain and offset to the measured parameter.
