WebOct 17, 2024 · One set of McMath-Pierce flux spectra has been reported on by Kurucz et al (1984) for the spectral band 296 to 1300 nm, not corrected for terrestrial absorption. The region 296 to 540 is essentially clear of terrestrial lines. Proceeding to the infrared, weak H2O lines begin to appear, then O2 bands beyond 579 nm and others in the infrared.

WebThe numbers in this article rely most heavily on direct satellite observations of reflected sunlight and thermal infrared energy radiated by the atmosphere and the surface. Earth’s heat engine does more than simply move heat from one part of the surface to another; it also moves heat from the Earth’s surface and lower atmosphere back to space. WebSunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as …
