The High Resolution VIS (HRVis) RGB
Information received from the three channels that contribute to the RGB combination
HRV | Optical thickness - High resolution (pixel: 1 km at Nadir) |
HRV | Optical thickness - High resolution (pixel: 1 km at Nadir)
The HRV channel is used in both red and green components to retain the high resolution information |
10.8 | (Classical IR Window channel) - Information about cloud top temperature |
Resulting colors for typical features
White | Thick convective cells |
Blue | Cold cloud tops, especially thin cirrus |
Yellow | Fog and low cloud |
Typical application areas
- Discrimination of cloud systems of different vertical extent
- Recognition of small-scale structures, especially in convective and low clouds/fog
This RGB is very useful for convective systems, as it lets us tell the thick Cb kernel apart from the thin high Cirrus anvil, as well as recognizing the overshooting tops. A convective summer case is presented below:
