Summary according to the RGB types
Snow RGB | |
Daytime RGB to monitor snow and to monitor low clouds or fog over snow. | |
|
Night Microphysics RGB | |
Nighttime RGB to monitor low clouds and fogs, to separate them from cloud-free surface. | |
|
Ash RGB | |
RGB can be used day & night. Similar to Dust RGB, but tuned for volcanic ash and SO2 gas plume detection. | |
|

Cyclogenesis | |
The stratospheric dry air protruding down is a signal for cyclogenesis. It can be best seen with the Airmass RGB having WV6.2, WV7.3 and IR9.7 (ozone channel) in it. During day and nighttime:
|
Convection | |
The microphysics of the cells helps to identify thunderstorms with severe updrafts. The HRV Cloud RGB provides information about the cloud top features in good spatial resolution. | |
