FAQ
What is a “mesonet”?
A mesonet is a network of automated weather stations that provides high definition weather coverage: areas of just a few hundred square miles and time intervals of several times per hour. This can be contrasted with the typical coverage that is thousands of square miles and hourly. Mesonets excel in providing high precision data particularly with highly variable elements like wind and precipitation.
How can my business or organization sponsor a South Dakota Mesonet station?
Sponsors play an important role in keeping the South Dakota Mesonet running. Coops, businesses, water authorities, even private individuals sponsor stations to get data for agricultural spraying, watershed management and as a community outreach opportunity. Contact Us about sponsoring a new or existing station in your area.
How should rainfall be interpreted?
South Dakota Mesonet stations use gauges intended to measure rainfall. In the event of snow, hail or other frozen/freezing precipitation, underreporting and delayed reporting can occur. If the current day’s low temperature is below freezing a warning will appear next to the reported rainfall to warn of this possibility.
How is soil temperature measured?
In keeping with typical agronomy practices, SD Mesonet Mobile reports soil temperature measured at a depth of four inches (if available).
Why isn't heat index or wind chill displayed?
Heat index and wind chill are displayed only when conditions are applicable. For heat index, this is when air temperatures are 80° and higher and relative humidities are 40% or higher. For wind chill, this is when air temperatures are 50° and lower and wind speeds are over 3 mph.
