Earth brightness temperature
WebApr 14, 2024 · The cloud-top brightness temperature can reflect the radiation emitted into space from the cloud-top and cloud-free or cloudless regions of the Earth’s surface. It is commonly referred to as black body temperature (TBB) . The lower is TBB, the higher the cloud-top height will be, which indirectly reflects the intensity of TC activity. WebConventionally, lower temperatures are represented by brighter shades of gray and white, while higher temperatures are represented by darker shades of gray. When you look at different visible satellite images, you will notice that they pretty much all look the same. Not so with infrared imagery (see the montage of images below).
