DOW7 Velocity (Ground; Greenfield, IA)
atmosphere NASA VEDA COG
In plain English

What it measures. Radar-measured ground-level wind speeds (in meters per second) inside the EF-4 tornado that struck Greenfield, Iowa on May 21, 2024, revealing the tornado's spinning motion.

How it's made. Captured by DOW7, a truck-mounted mobile Doppler-on-Wheels weather radar driven close to the storm.
