Radar Particle-Shape Reading of the Greenfield, Iowa Tornado (2024)

DOW7 Differential Reflectivity (Greenfield, IA)
atmosphere NASA VEDA COG
In plain English

What it measures. A radar measure (differential reflectivity, in decibels) of the shape and size of objects in the air inside the EF-4 tornado that hit Greenfield, Iowa on May 21, 2024, helping tell raindrops from tumbling debris.

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 researchers identify lofted debris and study what a tornado is picking up.
