Over 150 radars on your Mac.
RadarScope is a specialized display utility for weather enthusiasts and meteorologists that allows you to view NEXRAD Level 2 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 2 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 and now featuring Canadian radar products.
RadarScope displays tornado, severe thunderstorm, and flash flood warnings issued by the National Weather Service. You can browser 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 radar frames. 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 save the currently displayed map 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 2 radar data from NOAA’s public access web site or your Allison House subscriber account.
