SEVIRI

 

    SEVIRI (Spinning Enhanced Visible and InfraRed Imager)delivers daylight images of the weather patterns with a resolution of 3 km, plus atmospheric pseudo-sounding and thermal information. The High Resolution Visible (HRV) channel has a resolution of 1 km. The full disc view allows frequent sampling, every 15 minutes, enabling monitoring of rapidly evolving events. This aids the weather forecaster in the swift recognition and prediction of dangerous weather phenomena such as thunderstorms, heavy rain, fog and explosive development of small but intense depressions, which can lead to devastating windstorms.
