The optical atmospheric window is the optical portion of the electromagnetic spectrum that passes through the Earth's atmosphere, excluding its infrared part; [10] although, as mentioned before, the optical spectrum also includes the IR spectrum and thus the optical window could include the infrared window (8 – 14 μm), the latter is ...
Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. When the angle between the Sun and the horizon is less than 10 percent, as it is just after sunrise or just prior to sunset, sunlight becomes too red due to refraction for any colors other than those with a ...
Out of an average 340 watts per square meter (W/m 2) of solar irradiance at the top of the atmosphere, about 200 W/m 2 reaches the surface via windows, mostly the optical and infrared. Also, out of about 340 W/m 2 of reflected shortwave (105 W/m 2 ) plus outgoing longwave radiation (235 W/m 2 ), 80-100 W/m 2 exits to space through the infrared ...

Opacity of the Earth's atmosphere: the radio window spans larger wavelengths. The radio window is the region of the radio spectrum that penetrate the Earth's atmosphere . Typically, the lower limit of the radio window's range has a value of about 10 MHz (λ ≈ 30 m); the best upper limit achievable from optimal terrestrial observation sites is ...
