You are probably talking about model updates. The FAQ answers your question:
@Peggotty Hello, the "Windy.app" is a completely different application and there is no association with us, except we share a similar name.
@Peggotty Thank you, we plan to change the text.
Windy visualises weather models like ECMWF, GFS, ICON…. These models probably integrate ASCAT data during the assimilation phase.
But Windy does not make its own prediction. When Windy displays Wind forecasts, these are the forecasts from these models, nothing else. So Windy does not incorporate ASCAR data.
@idefix37 I agree, please implement weather routing and you will have a killer app
