By combining data from both weather radars and satellites, Ventusky can now display rainfall in real time almost anywhere on Earth. This allows an unprecedented global coverage, even across the oceans.

Accurate information about where it’s raining right now is absolutely essential. Numerical weather models can simulate precipitation, but they are still just calculations. The most accurate insight comes only from measured data. That’s where weather radars come in: specialized instruments that monitor rainfall within several hundred kilometers. Their drawbacks are limited reach, and the fact that they can’t be placed over oceans. Satellites fill this gap: while slightly less precise, they capture rainfall data across vast areas, including remote ocean regions.

To visualize rainfall globally, it’s therefore necessary to merge a huge number of data sources. That’s exactly what we focus on at Ventusky – processing data from hundreds of radars worldwide along with multiple satellites in orbit. We are constantly expanding this network, and in recent days we’ve made a big leap forward: we’ve added new satellite data to the radar network and doubled the resolution of the entire layer.

Earlier this spring, we also accelerated radar updates, reducing the time step from 10 minutes to just 5 minutes. The result is a far more accurate and detailed real-time picture of rainfall, available anywhere on Earth.

We have made a little comparison video to highlight the advantage of our new Radar Layer. See the difference?

And while you may notice some services currently struggle with live radar data, Ventusky is leaping forward — not only maintaining global coverage, but improving it dramatically. For everyday planning, storm tracking, or critical safety alerts, Ventusky now gives you better tools than ever before.
