The mobile mesonet is a vehicle intended to take surface observations of temperature, pressure, humidity, wind, and even solar radiation in and around storms and storm environments. Originally designed in 1992 by scientists and technicians from NSSL and The University of Oklahoma, these “probes” have undergone significant improvements over the years. Now, highly modified trucks are used to take these observations using a custom-designed roof rack and a complex of computer and communication equipment. Given that operating in severe weather comes with severe weather hazards, researchers added a hail cage to the vehicles to protect the windshields from damage.
