This AI weather startup is out-forecasting government agencies
Windborne Systems has launched an AI weather forecasting tool called WeatherMesh 6, which claims to provide more accurate predictions than traditional models. The startup, founded by Stanford students in 2019, has improved its forecasting capabilities by integrating data from its weather balloons. WeatherMesh 6 offers hourly forecasts with high resolution, positioning it as a competitive alternative to established systems like the ECMWF.
- ▪Windborne Systems' WeatherMesh 6 is said to be as accurate five days out as traditional forecasts are the day before.
- ▪The new model produces forecasts every hour, compared to the six-hour intervals of traditional models.
- ▪Windborne currently operates about 400 balloons globally to gather sensor readings for its forecasts.

Opening excerpt (first ~120 words) tap to expand
A new AI weather forecasting tool released today by the startup Windborne Systems offers more frequent and accurate predictions on key variables than the world-leading system developed by European governments, thanks to advancements in how sensor readings are fed into deep learning models. Founded by a group of Stanford students in 2019, Windborne began by building a better weather balloon, with the idea of selling weather data. But the arrival of the weather-forecasting deep learning models in 2022, the team realized they could capture more value by building their own model as well.
