What's in it
Live Level II radar
Reflectivity, velocity, spectrum width and the dual-polarisation moments, straight from the station's own volume as it comes in. Range rings, a scale bar, and a map you can pan across the country.
A flat radar plan view over a map, with a storm in reds and yellows and a National Weather Service warning boundary outlined around it.
The 3D tilt stack
One cell, the area around it, or the whole scan out to 230 kilometres. One finger orbits, two pan the ground, pinch takes you from the entire picture down into a single core. The map lies on the floor under all of it, so a return at 200 kilometres on bearing 250 is a place and not a number.
A wide three-dimensional radar box covering hundreds of kilometres of coastline, with the scope and radius controls visible at the bottom of the screen.
A single storm cell rendered in three dimensions, seen from near ground level, its heaviest returns forming a core inside the column.
Velocity draws in 3D too, so an inbound-outbound couplet is a shape sitting inside the core rather than a smudge on a plan view.
A storm cell rendered from velocity data in three dimensions, showing air moving toward the radar on one side and away on the other.
Storm cells
Every cell in the volume, strongest first, with peak intensity, echo top, the height its maximum sits at, and VIL. Found on the phone from the gates, not read off someone else's list.
A list of storm cells over a radar view, each row showing a small plan thumbnail with peak intensity, distance and echo top.
Cross-sections
A vertical slice through the storm along the radar's own radial. Every beam is drawn at the size it actually sampled, and the space no beam reached is left empty rather than filled in.
A vertical cross-section through a storm, height against distance, with the radar beam paths drawn as diverging lines and the space between them left empty.
The archive
Pick a station, a date, a start and a length, and that span loads into the same loop. Sunset and sunrise are offered as starts, because the things worth going back for happen within minutes of them.
The archive screen with a station, a date, a sunset start and a two-hour length selected.
Watches and warnings
National Weather Service boundaries drawn where they are, over the radar they are about. Open one and you get the Weather Service's own text, unedited. Turn on notifications and the ones near you arrive as a push.
Not for use in life-safety decisions. Follow official warnings.
A National Weather Service severe thunderstorm warning shown in full, with its headline, expiry time and official text.
AR
Put the storm on the table and walk around it, or hold the phone up at the real one and see the shape where it is.
A storm 60 kilometres away is 60 kilometres away. Radar sees rain, not cloud.
