Ground Truthing
The SKYWARN program, which teaches people how to spot tornadoes, funnel clouds, wall clouds, and other severe weather phenomena, is offered by the National Weather Service. Used in tandem with Doppler radar information, eyewitness reports can be very helpful for warning the public of an impending tornado, especially when used for ground truthing.
Other spotter groups such as the Amateur Radio Emergency Service, news media, local law enforcement agencies/emergency management organizations, cooperative observers, and the general public also relay information to the National Weather Service for ground truthing.

Famous quotes containing the word ground:
“I saw young Harry with his beaver on,
His cuisses on his thighs, gallantly armed,
Rise from the ground like feathered Mercury,
And vaulted with such ease into his seat
As if an angel dropped down from the clouds
To turn and wind a fiery Pegasus,
And witch the world with noble horsemanship.”
—William Shakespeare (1564–1616)
