RainViewer gets radar data from different sites across the Internet for free therefore we share all this data for everyone for free as well. Use whatever you want. We do not guarantee the availability of radar data. We do not conclude contracts with owners of this data, that’s because owners can kindly ask us to remove their data from the RainViewer, change the format or stop sharing this data at all. We’re trying to keep radar data as much as possible, but sometimes they stop just serving the images.
