Limitations of images


	Limitations of images
	Causes Reflection Scattering Absorbption	Effects Clouds prevent light visible light and infrared radiation from reaching a satellite because they are reflected from the bottom of the cloud. Radar can penetrate clouds but it can then be scattered by raindrops. Blue light is scattered by molecules of nitrogen and oxygen, due to its high frequency and short wavelength. This prevents the blue light be reflected back to the satellite and therefore is a limitation of the image. This is why the sky is blue too. Larger molecules can also scatter green and red light. Infrared and U.V are both absorbed by certain molecules in the earth’s atmosphere. U.V by ozone and infrared by greenhouse gases such as carbon dioxide and water vapor.
