Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface, thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation.

How does infrared affect the environment?
The earth’s surface and the clouds above it absorb radiation from the sun’s rays and re- emit it as infrared radiation back out into the atmosphere. The trapped radiation causes increased temperatures and changes in weather that could be harmful to people and animals.
Why is infrared light important to Earth?
Infrared radiation is responsible for warming Earth’s surface and atmosphere. Infrared light is on the opposite side of the spectrum from ultraviolet light. This radiation has a wavelength of >700 nm and provides 49.4% of solar energy 9.
How do we use infrared on earth?
Infrared sensing One of the most useful applications of the IR spectrum is in sensing and detection. All objects on Earth emit IR radiation in the form of heat. This can be detected by electronic sensors, such as those used in night vision goggles and infrared cameras.
What is the effect of infrared to a person or environment?
Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.
What are the harmful effects of infrared?
Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.
What are the advantages and disadvantages of infrared waves?
1) Infrared transmission requires minimum power to operate and can be set up at a low cost. 2) This is a secure way to transfer data between devices as the signal cannot pass beyond a room or chamber. 1)The speed of data transfer in infrared is slow. 2) Infrared can be used for a small range distance.
How does infrared light effect global warming?
By increasing the amount of greenhouse gases in the atmosphere, humans are increasing the atmosphere’s absorption of infrared light, thereby warming Earth and disrupting global climate patterns. When people produce greenhouse gases, energy leaves Earth even more slowly – raising Earth’s temperature.
What is infrared radiation and global warming?
When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet’s internal energy increases and the surface gets hotter. Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.
What are examples of infrared?
The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared.
Why do scientists use infrared to image the Earth?
Why use the infrared to image the Earth? While it is easier to distinguish clouds from land in the visible range, there is more detail in the clouds in the infrared. This is great for studying cloud structure. For instance, note that darker clouds are warmer, while lighter clouds are cooler.
What can you do with infrared?
Infrared light has been linked to many benefits. These include: Promoting wound healing and tissue repair. Stimulating healing of ulcers and slow-healing wounds.
How does infrared light interact with matter?
Infrared is absorbed more strongly than microwaves, but less strongly than visible light. The result of infrared absorption is heating of the tissue since it increases molecular vibrational activity.
Can infrared blind you?
All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. The infrared light needs to be extremely intense to cause harm. In extreme cases, if the eyes absorb too much infrared light, they can be irreversibly damaged.
What does infrared do to your skin?
New scientific research has revealed that one third of infrared (IR) light can penetrate into the deeper layers of the skin, triggering heat induced responses such as inflammation, hydration loss and the degradation of collagen and elastin.
