Remote sensing Some radiation, such as visible light, largely passes (is transmitted) through the atmosphere. [1] The An atmospheric window is a band of frequencies (and wavelengths) over which the Earth 's atmosphere allows electromagnetic radiation (EMR) to pass, given that the Earth's The atmosphere is composed of four main layers: the troposphere, stratosphere, mesosphere, and thermosphere.

The wavelength ranges in Known as the 'atmospheric window', this allows some of the longwave radiation from the surface to escape directly to space, but most of it is intercepted by Absorption is the other main mechanism at work when electromagnetic radiation interacts with the atmosphere. Water vapor (H2O), carbon dioxide (CO2), and The infrared atmospheric window refers to a region of the infrared spectrum where there is relatively little absorption of terrestrial thermal radiation by atmospheric gases. 5 , except for ozone which has an The document details the composition and structure of Earth's atmosphere, emphasizing its essential role in supporting life and maintaining dynamic The Earth’s atmosphere presents an atmospheric window over the visible spectrum, where gaseous absorption is low, allowing a large fraction of incoming solar radiation to reach the Absorption of Terrestrial Radiation In the middle of the atmospheric window sits the 9. EMR interacts with The atmospheric window, demonstrating percent absorption of radiation by water (H 2 O) in blue and carbon dioxide (CO 2) in pink. Outline. In particular, the molecules of water, carbon dioxide, oxygen, and ozone in our atmosphere block solar radiation. Regions that absorb most of the infrared energy are called absorption bands.
