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

What it measures. Radar-measured wind speeds (in meters per second) toward and away from the radar inside the EF-3 tornado that struck Harlan, Iowa on April 26, 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.

How & where you'd use it. Helps scientists gauge how fast a tornado's winds are spinning and assess its strength.
