Mesonet information placard

The Dr. Kenneth C. Crawford Oklahoma Mesonet Site. The Oklahoma Mesonet is a world-class network of environmental monitoring stations that delivers real-time measurements of atmospheric and soil conditions continuously in every county in Oklahoma. The network was designed and implemented by scientists and engineers at the University of Oklahoma and Oklahoma State University.

Explanation of sensors

Each mesonet station has sensors for measuring 10-meter wind speed and direction, communications antennas, and a lightning rod at the top. Just below, a sensor measures the temperature at 9m above ground level (AGL). Another temperature sensor is at 1.5m, allowing mesonet stations to identify inversion conditions. Also lower down the tower are: a solar panel and sensors for solar radiation measurements, 2m wind speed, relative humidity and barometric pressure. Nearby the tower are two sets of soil temperature and moisture measurements, one under bare ground and one under vegetation characteristic of the site. Two rain gagues are surrounded by baffles that create turbulence that helps wind-driven rain fall into the buckets. Data loggers and batteries complete the system.

Dr. Smith explains the radiometers that either were or will be installed in the CLAMS2 trailer.


This is the lidar. The mechanisms allow it to be raised through the trailer roof for taking data.
