Boston-based Tomorrow.io began as a software company that offered hyper-precise, street-level weather forecasting. Now it has set its sights on space. The company recently launched Tomorrow-R1, what it claims is the world’s first commercially built weather-radar satellite, via SpaceX’s Falcon 9 rocket. There are very few atmospheric radars orbiting the earth currently, and all were built by government agencies. The U.S. has one, operated by NASA. Tomorrow.io used proprietary software not just to predict but also to help companies plan for severe weather. The information it used came from government radar, data satellites, weather stations, cellular signal attenuation, and even connected vehicles with wiper and temperature sensors — what its CEO and co-founder, Shimon Elkabetz, called the “weather of things.” The new radar satellite, however, will offer a much broader scope of data. “We’re going to create a significant revolution when it comes to weather forecasting and climate modeling and be able to help the National Hurricane Center hopefully have better hurricane forecasting and help insurance companies insure farmers in India and Brazil, and help airlines fly from JFK to London in a much safer route and by wasting less fuel,” said Elkabetz.
