Ask the Weather Guys: What is a mesonet?

JOHN HART, STATE JOURNAL
A snow squall — an example of a mesoscale event — affects pedestrian and vehicle traffic Dec. 9 in Madison, Wis.
Q: What is a mesonet?
A: In meteorology and climatology, a mesoscale network, or mesonet, is a network of automated environmental monitoring stations designed to observe meteorological phenomena on the mesoscale. In meteorology, “mesoscale” refers to weather events that range in size from about 1 mile to about 150 miles.
Mesoscale events last from several minutes to several hours. Thunderstorms, snow squalls and wind gusts are examples of mesoscale events. Due to the space and time scales associated with mesoscale phenomena, weather stations comprising a mesonet are spaced closer together and report more frequently than the larger synoptic scale observing networks run by the National Weather Service.
Just recently, UW-Madison received funding from the Wisconsin Alumni Research Foundation (WARF) and the United States Department of Agriculture (USDA) to purchase and install a mesonet across Wisconsin. A Wisconsin Environmental Mesonet and the data provided will support a wide range of research interests, including applications that involve many collaborators across the state.
A majority of Midwest states already have some type of mesonet guiding everyday use and decision-making. Wisconsin will now join that infrastructure.
Mesonets provide real-time weather and soil data for anyone to use. This helps support farmers, crop consultants and extension agents, support fire weather prediction, reduce economic losses in agricultural production, assist in weather warning issuance and forecasting, assist in emergency planning and preparedness, improve public safety, and support K-12 education.
Mesonets also provide data to a wide variety of researchers, scientists and teachers. Data from existing mesonets support a variety of weather and agriculture models. Observations from a mesonet can help support and improve the development of local temperature forecasts, as well as predictions for water demand by crops.

The nonprofit "Feeding People Through Plants" founder Andy Robledo set out to find homeless people and give them large orange tents used for ice fishing to replace other tents and shelters that are inadequate for severe winter weather. "Last November is when it all started," said Robledo. "I lived in Pilsen and I drive by these camps every single day and I noticed new tents popping up every single day." Robledo said one day he returned to his blue pickup truck and someone had broken in, although he intitally didn't notice anything missing. "One of my blankets was missing from my truck. That's what got me. That's what did it. That's what motived me…at that moment I said I'm not doing enough." (AP Photo/Erin Hooley)
