The shape of debris and rain in the Greenfield, Iowa tornado, from the DOW7 mobile radar (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.
