TeachMeFinance.com - explain Infrared Satellite Imagery Infrared Satellite Imagery The term 'Infrared Satellite Imagery' as it applies to the area of the weather can be defined as ' This satellite imagery senses surface and cloud top temperatures by measuring the wavelength of electromagnetic radiation emitted from these objects. This energy is called 'infrared'. High clouds are very cold, so they appear white. Mid-level clouds are somewhat warmer, so they will be a light gray shade. Low cloud are warmer still, so they appear as a dark shade of gray or black. Often, low clouds are the same temperature as the surrounding terrain and cannot be distinguished at all. The satellite picks up this infrared energy between 10.5 and 12.6 micrometer (um) channels. '.
