The Oklahoma Mesonet was commissioned on January 1, 1994 and consists of 120 automated stations covering Oklahoma. There is at least one Mesonet station in each of Oklahoma's 77 counties.

At each site, the environment is measured by a set of instruments located on or near a 10-meter-tall tower. The measurements are packaged into "observations" every 5 minutes, then the observations are transmitted to a central facility every 5 minutes, 24 hours per day year-round.

The Oklahoma Climatological Survey at OU receives the observations, verifies the quality of the data and provides the data to Mesonet customers. It only takes 5 to 10 minutes from the time the measurements are acquired until they become available to the public.

Forecast data on our website and mobile apps is provided by the National Weather Service (NWS). We are especially grateful for the support and partnership with our local NWS offices covering Oklahoma, including the Norman, Tulsa, Amarillo, and Shreveport offices.

Definition of "Mesonet"

"Mesonet" is a combination of the words "mesoscale" and "network".

In meteorology, "mesoscale" refers to weather events that range in size from about one mile to about 150 miles. Mesoscale events last from several minutes to several hours. Therefore, mesoscale weather events are phenomena that might go undetected without densely spaced weather observations. Thunderstorms, wind gusts, heatbursts, and drylines are examples of mesoscale events.

A "network" is an interconnected system.

Thus, the Oklahoma Mesonet is a system designed to measure the environment at the size and duration of mesoscale weather events. For more information about Mesonets across the U.S., visit the National Mesonet website and the Mesonet Essentials website
