Picture a big group of weather stations spread out all over an area, like a whole state. These weather stations are called a mesonet - it's short for "mesoscale network." They all work together to measure things like temperature, humidity, wind speed, and precipitation, all at different spots. The mesonet gathers all this information and sends it back to people who need to know about the weather, like meteorologists and the people who decide when to issue weather alerts. Just like how you need to look at all the pieces of a puzzle to see the whole picture, the mesonet helps give us a better understanding of the whole weather situation across an entire region.
