RadarScope is a specialized display utility for weather enthusiasts and meteorologists that allows you view NEXRAD Level 3 and Super-Resolution radar data along with Tornado, Severe Thunderstorm, Flash Flood and Special Marine Warnings, and predicted storm tracks issued by the U.S. National Weather Service. It can display the latest reflectivity, velocity, dual-polarization, and other products from any NEXRAD or TDWR radar site in the United States, Guam, Puerto Rico, Korea, and Okinawa, as well as data from Environment Canada and Australian Bureau of Meteorology radars. These aren't smoothed PNG or GIF images, this is native 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 weather radar data.

RadarScope displays tornado, severe thunderstorm, flash flood, and special marine warnings issued by the U.S. 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 and pan on the map using the mouse, trackpad, or touch screen. Select one of the 289 different radars in the United States, Canada, Australia, Korea, Puerto Rico, Guam, or Okinawa. Tap the play button to download and animate over recent images. 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 export the currently displayed map to several common image formats.

Meanwhile, RadarScope will retrieve and display updated data automatically and intelligently (approximately every 2 to 10 minutes, depending on the radar scan strategy). You can display radar data from our servers, NOAA's public access web site, or your Allison House subscriber account.
