Private weather isn’t new. In 2013, an article from the Wharton School estimated that a global weather forecasting industry of around 350 companies was pulling in around about $3 billion annually. In 2017, NOAA estimated that the sector in the U.S., which today encompasses everything from hourly road surface forecasts for long-haul truckers to drought forecasts for individual farms, was worth $7 billion. Reports suggested it was growing at a rate of around 10-15% annually.
Through a global infrastructure that includes 17 weather satellites, radar, weather balloons, buoys and ground-based weather sensors, NOAA gathers 6.3 billion observations each day. (The agency even has its own uniformed service, as well as a fleet of planes and ships.) It supplements this data with observations from foreign governments and processes it all using numerical weather prediction models.
