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

2 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 RGBs with the HRV Channel: Introduction

3 Recommended Range and Enhancement: BeamChannelRangeGamma Red12 (HRV)0 …+100 %1.7 Green12 (HRV) %1.7 Blue09i (IR10.8i) K1.0 RGB 12,12,09i ("HRV Clouds")

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 to distinguish between thick Cb clouds and Ci anvils
