Help us test our new Weather Radar overlay

As we are continuously improving Windy, we’ve never stopped thinking to create – and expand – the 'Weather Radar' feature. However, this service is depended on various data providers, and each country has a different policy regarding the management of these data (see this link).

Weather radar, also called Doppler weather radar or Weather surveillance radar (WSR), is a reflectivity measurement device used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.) or amount of predictable water in clouds. Returned echoes from targets ("reflectivity") are analyzed for their intensities to establish the precipitation rate in the scanned volume.

So far, our radar layer has been covering the USA (including Hawaii and coastal parts of Alaska), South Korea and a couple of islands in the North Pacific Ocean and the Caribbean.

After a period of hard work, now we are excited to announce that the long-anticipated Weather radar for a large part of Europe is out! Our Weather Radar is covering the area from Spain to Finland (see this table). We are gathering radar data for other countries and we will be adding them slowly but surely.
