APPLICATIONS OF METEOSAT SECOND GENERATION (MSG) RGB COMPOSITES WITH CHANNEL 12 AND THEIR INTERPRETATION
RGBs with the HRV Channel: Introduction • In order to preserve the high resolution of the HRV channel, it should be assigned to 2 colours • The HRV has a three times higher resolution than the other channels, i.e. a zoom factor of 3 is needed for the IR channels
