Cross-Section + 3D Volume

Inside the storm.

Storm Cross-Section slices straight through the updraft to show hail lofted above the freezing level, and 3D Storm Volume turns the same scan into a rotatable scene you can walk around. Premium

Watch the radar turn.

LIVE Sweep streams each ray the moment the radar collects it. The beam sweeps around and paints the storm arc by arc, turning at the radar's real rotation rate, on any Level 2 product and any tilt, at every NEXRAD radar. Premium

Replay any storm since 1991.

Every frame on this page, from first echo to hook, came from the historical radar archive in Echoes: raw NEXRAD data back to 1991. Premium

Moore had been here before. May 3, 1999, replayed in Echoes.

Velocity and dual-polarization radar data side by side
Reflectivity + Velocity

Side by side.

In velocity data, rotation is unmistakable: winds toward the radar beside winds away from it. Dual Products puts reflectivity and velocity on one synced map, so the couplet shows up right next to the shape that caused it. Premium
