How It Works

Almost every country has installed meteorologic equipment called “weather radar”, “rain radar”, or “Doppler radar.” It scans the sky and allocates precipitation particles, determining their size and velocity. That magic equipment can easily track even severe weather conditions such as tornado or hail. RainViewer receives that data from a variety of weather radar data sources and creates one large and highly accurate precipitation map for the covered areas. This technology allows us to build outstanding products on top of that information, such as severe weather alerts, rain forecast map, storm pathways, etc.
