Radar sign of flying debris in the 2024 Greenfield tornado, from Doppler on Wheels radar (DOW7)

DOW7 Correlation Coefficient (Greenfield, IA)
atmosphere NASA VEDA COG
In plain English

What it measures. A radar measure (called correlation coefficient) that reveals how uniform the objects in the air are inside the EF-4 tornado that hit Greenfield, Iowa on May 21, 2024. Low values flag lofted debris, marking where the tornado is tearing things apart.

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. Lets forecasters and researchers confirm a tornado is on the ground and causing damage.
