Although ESA’s small Arctic Weather Satellite was built as a demonstrator for future constellation called EPS-Sterna, the European Centre for Medium-Range Weather Forecasts is now incorporating its data into its operational weather forecast system – highlighting the fact that small satellites delivered in record time can achieve great things.
For the first time, the Arctic Weather Satellite operates in the ‘sub-mm’ spectral band – wavelengths shorter than 1 mm – to also provide fresh insights into ice clouds, as shown in the image above. The mission proves that high-quality, passive microwave measurements can be delivered by a small, cost-efficient satellite.
