ESA’s Arctic Weather Satellite is designed to show how a potential polar-orbiting constellation of satellites could provide data for very short-term weather forecasts and nowcasts in the Arctic, a region that lacks these kind of forecasts. Importantly, the constellation would also allow for more accurate forecasting around the world.
Coincidently the Arctic Weather Satellite resembles a bird in flight, which ties in nicely with the name of the potential satellite constellation being ‘Sterna’. A genus of birds that includes the Arctic Tern.
