Arrow Clouds Types in Satellite Imagery

A PowerPoint presentation on determining cloud types in visual and infrared satellite imagery.


Arrow Cloud detection (IR vs VIS)

Visible (VIS) satellite imagery and infrared (IR) imagery have different ways of detecting clouds. Visible imagery is produced by the sun's rays reflecting off of clouds. Infrared is produced by sensing the emitted radiation coming off of clouds. The temperature of the cloud will determine the wavelength of radiation emitted from the cloud. Some advantages of visible imagery is that it has a higher resolution, shows cloud texture better, and can be used to get a good idea of the thickness of the cloud. Some advantages of infrared imagery is that is can be used day and night, it can be used to determine the temperature of cloud tops and earth surface features, and it can be used to get a general idea of how high clouds are.
