The Golden Age of Weather Radar Data

WeatherWall has long supported NEXRAD, the U.S. weather radar network. It was the natural choice because the data is available for free, in near real time, with a public domain (CC0) license. For years, NEXRAD was one of the best sources of freely available weather radar data. In the past few years, more radar data has become available around the world. Europe’s new open data rules are helping bring radar data to everyone. Japan, Mexico, and Canada also share weather radar data, and Australia’s Bureau of Meteorology offers radar data through free and paid services.

There are more countries with weather radars, including Colombia and Brazil. I am still looking for publicly accessible, near-real-time radar volume data from those countries. I hope more of it becomes available in the coming years. There is also a new wave of public-private partnerships building gap-filling radars across the U.S. Unfortunately, data from many of these radars seems difficult to access so far.

I love being able to pick a radar and look at a storm in detail. Depending on the radar, you can examine reflectivity, velocity, and other products at different angles. With more countries sharing their data, we can do that in more places than ever.

WeatherWall is the only app to support all 455 radars

WeatherWall brings 455 radars together in one app. You get 347 included radars, with another 108 available through an optional Weather Pulse subscription.

Here is a breakdown of the networks and how to access them in WeatherWall.
