-- A gradient (change) in temperature, pressure, and humidity with altitude can bend the path of radio waves. The effect is independent of frequency. -- Ionized atmosphere, such as intermittently arises between roughly 70 to 250 miles above the surface, reflects radio waves at the lower frequencies ... below perhaps 35 MHz depending on the depth and intensity of the ionized layers. -- The presence of rain, sleet, and fog can attenuate the radio waves by absorbing some of the RF energy. The effect is greater at higher frequencies (essentially negligible below perhaps 8 GHz). -- Atmospheric gases alone exhibit non-negligible absorption of RF at high microwave frequencies, e.g. 28 GHz and above. -- High winds can have a significant effect on the transmission of E&M waves, not so much in any way that would have interested Maxwell, but rather when an antenna is blown off path due to loose or under-rated mounting hardware. Ask me about it !

What two features of earth protect us from the sun's radiation?
strong magnetic field deflects charged particle radiation around the earthozone layer absorbs much of the ultraviolet electromagnetic radiation as it enters the atmosphere
If the atmosphere had no single particle in it how would the sky appear during daytime?
Black
Do meteors glow as they collide with earth's atmosphere?
Yes and No, When they are flying down toward earth the are burning in the atmosphere thus making them appear to glow.
How does the atmosphere impact the biosphere?
first guh its the weather climate
What is the earths sunblock?
The ozone layer acts as a sort of 'sunblock' for the earth, limiting the amount of UV radiation that enters the atmosphere.
What is the source of radiation for both the earth's atmosphere and the greenhouse effect?
The Sun is the primary source of radiation for both the Earth's atmosphere and the greenhouse effect. Solar radiation enters the atmosphere, warms the Earth's surface, and is re-radiated as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, leading to the greenhouse effect.
What does the atmosphere do to some of the radiation?
It absorbs some of the radiation. The radiation is UV rays.
What gas absorbs UV radiation in the Earth's atmosphere?
Ozone gas absorbs UV radiation in the Earth's atmosphere.
What is the source of radiation for both the Earth's atmosphere and the greenhouse?
The primary source of radiation for both Earth's atmosphere and the greenhouse effect is the sun. Solar radiation warms the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet.
Why is the atmosphere is heated cheifly by radition from Earth's surface rather than by direct solar radiation?
The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
Why do astronauts need protection against radiation?
1. on earth light and radiation from space is filtered in the atmosphere, however when going out of the atmosphere radiation can become unpleasant.
What form of radiation can be shielded by the earth's atmosphere?
The form of radiation shielded by atmosphere is Ultraviolet. The Ultraviolet is a part of radiation released by our star sun.
Which form of radiation given off by the earth causes heating of the earth's atmosphere?
Infrared radiation is the form of radiation given off by the Earth that causes heating of the Earth's atmosphere. This radiation is absorbed by greenhouse gases in the atmosphere, which traps heat and warms the planet.
What are the differences between long wave radiation and shortwave radiation in terms of their impact on the Earth's atmosphere?
Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere. Shortwave radiation, such as sunlight, is absorbed by the Earth's surface and then re-emitted as longwave radiation. This difference in wavelengths affects how energy is distributed in the atmosphere, with longwave radiation playing a key role in the greenhouse effect and shortwave radiation driving the Earth's climate system.
Does Mars receive radiation from the Sun?
Yes. Earth receives radiation. The atmosphere acts as a filter. The atmosphere of Mars is thinner than Earth. Mars receives radiation also.
What form of radiation can be shielded by earths atmosphere?
The form of radiation shielded by atmosphere is Ultraviolet. The Ultraviolet is a part of radiation released by our star sun.
How does solar radiation leave earths atmosphere?
Solar radiation leaves Earth's atmosphere through a process called reflection and absorption. Some of the radiation is reflected back into space by clouds, gases, and particles in the atmosphere. The remaining radiation is absorbed by the surface of the Earth, where it is converted into heat energy.
