  1. APPLICATIONS OF METEOSAT SECOND GENERATION (MSG) RGB COMPOSITES WITH CHANNEL 12 AND THEIR INTERPRETATION

  2. 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

  3. RGB 12,12,09i ("HRV Clouds") Recommended Range and Enhancement: Beam Channel Range Gamma Red 12 (HRV) 0 …+100 % 1.7 Green 12 (HRV) 0 ... +100 % 1.7 Blue 09i (IR10.8i) +323 ... +203 K 1.0

  4. Ch.12 HRV Ch.12 HRV Ch.09i IR10.8i

  5. Colour Interpretation of RGB 12,12,09i Images

  6. Example: river valley fog over Germany

  7. Example: severe convective storms over Spain

  8. Comparison HRV vs RGB 12,12,09i MSG-1, 13 June 2003, 14:00 UTC The RGB 12,12,09i helps to detect thin Ci clouds and todistinguish between thick Cb clouds and Ci anvils
