RadarScope is a specialized display utility for weather enthusiasts and
meteorologists that allows you to view NEXRAD Level 3 radar data and severe
weather warnings. It can display the latest reflectivity, velocity, and other
radar products from any NEXRAD radar site in the United States, Guam and
Puerto Rico. These aren't smoothed PNG or GIF images, this is real Level 3
radar data rendered in its original radial format for a high level of detail.

Whether you are scanning reflectivity for a mesocyclone's tell-tale hook echo,
trying to pinpoint the landfall of a hurricane's eye wall, or looking for
small features like velocity couplets in the storm relative radial velocity
product, RadarScope gives you the power to view true radial NEXRAD weather
radar on your Mac.

RadarScope displays tornado, severe thunderstorm, and flash flood warnings
issued by the National Weather Service. You can browse the list of active
warnings in the information sidebar, select a warning to view the details, and
even zoom to the selected warning on the map.

Zoom in and out on the map using the mouse or pinch gestures on multi-touch
trackpads. Click and drag to scroll around the map. Select one of the 155
different radar sites using buttons on the map, the full radar list in the
sidebar, or your list of saved favorites in the menu bar. Tap the play button
to download and animate up to 20 frames of radar data. Dynamically display the
names of over 25,000 cities and towns on the map as you zoom and scroll. Move
the cursor over the color legend to see the data value associated with each
color. You can also copy the currently displayed map to the clipboard or save
it in several common image formats.

Meanwhile, RadarScope will retrieve and display updated data automatically and
intelligently (approximately every 5 to 10 minutes, depending on the radar
scan strategy).

You can display Level 3 radar data from NOAA's public access web site or use
your Allison House subscriber account for radar data (recommended).
