Introducing RadarScope 3.9

We’re pleased to announce RadarScope 3.9. It’s available today for iOS, macOS, and Android, with Windows and tvOS to follow soon. Today’s update includes many new features and improvements.

Australian Radars

We added support for 51 radars operated by the Australian Bureau of Meteorology. Several of these radars provide a full product suite of reflectivity, velocity, and spectrum width at four tilts. Others provide reflectivity and velocity or only reflectivity.

New Canadian Radars

The Canadian government is in the midst of a multi-year effort to upgrade their radar network. RadarScope 3.9 adds data for five new radars: Radisson (CASRA), Blainville (CASBV), Foxwarren (CASFW), Smooth Rock Falls (CASRF), and Spirit River (CASSR). These new radars feature an improved product suite including high-resolution reflectivity, velocity, spectrum width, differential reflectivity, correlation coefficient, and specific differential phase at four tilts. As additional radars are upgraded and the data are made available to us, we’ll add support for them.

Super-Res Dual-Pol Products

We’re expanding our suite of dual-polarization products for NEXRAD radars to include super-resolution versions of differential reflectivity, correlation coefficient, and specific differential phase at all four tilts.


Improved Server Infrastructure

We’re now serving all radar and lightning data to RadarScope 3.9 through Amazon Web Services, giving us increased redundancy, bandwidth, and load-scaling capabilities. Older versions of RadarScope will continue to rely on our data center in Dallas, so upgrade to 3.9 as soon as you can for the best experience!

Snow Squall Warnings

The U.S. National Weather Service (NWS) began issuing snow squall warnings last November. RadarScope 3.9 adds support for these. Snow squall warnings are intended to warn the public of reduced visibility due to lake effect and frontal snow squalls. NWS criteria for issuing a snow squall warning include visibility of less one quarter of a mile, sub-freezing temperatures on the ground, expected duration of less than an hour, and dangerous or life-threatening conditions. You can learn more about snow squall warnings on Wikipedia and the NWS web site:

Android Notch Support

Android 9 added support for displays with notches or cutouts for cameras and other sensors. RadarScope 3.9 adds support for notched displays when running on Android 9 or higher.

Note To Beta Testers

If you’ve been helping us beta test RadarScope 3.9, you may need to take some extra steps to update to the official release. Customers on iOS and tvOS running TestFlight builds will need to manually install version 3.9 from the App Store. After installing, you may need to open the Pro tab in the settings and hit the Restore button to restore your Pro subscription. If you have any trouble at all moving from the beta to the final release our support team is happy to help.
