Solar radiation plays a crucial role in shaping the Earth's atmosphere by driving weather patterns and influencing climate. It heats the Earth's surface, which in turn warms the air above it, causing convection currents that lead to wind and weather systems. Additionally, solar radiation affects the chemical composition of the atmosphere, influencing processes such as photosynthesis, and the formation and breakdown of ozone. Overall, it is fundamental to maintaining life and regulating temperatures on the planet.
Solar flares can't directly harm humans on Earth because our atmosphere protects us from their radiation. However, they can disrupt communications, GPS systems, and power grids which could indirectly affect human activities on Earth. Astronauts outside Earth's atmosphere are at risk of increased radiation exposure during a solar flare event.
Earth's land and sea absorb solar radiation, then reradiate it to the air
Radiation budget is Earth's atmosphere. The Earth's atmosphere has more solar energy than it radiates back to space.
The higher in the sky the sun is the more solar radiation received at the surface. This is because as the sun gets higher in the sky, there is less atmosphere blocking the sun's rays. Imagine the sun going through the atmosphere at a 90 degree angle. The thickness of the atmosphere let say is x thick. As the sun hit the surface at a lower angle, the thickness of the atmosphere has to go through more atmosphere to get to the surface. So the thicker atmosphere blocks more of the sun's rays.
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
the atmosphere absorbs heat from solar radiation; which varies with latitude and seasons
The increase in carbon dioxide in the atmosphere means that more solar radiation (in the form of infra-red heat from the warmed earth) is absorbed in the atmosphere and prevented from escaping to space. It will not change the transmission of incoming solar radiation through the atmosphere.
Volcanic ash particles can reflect sunlight back into space, causing a cooling effect on Earth's surface. However, ash can also absorb and scatter incoming solar radiation, potentially leading to local warming of the atmosphere. Additionally, the presence of volcanic ash in the atmosphere can impact air quality and visibility.
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.
Greenhouse gases trap heat in the Earth's atmosphere, causing an increase in temperature. This leads to a decrease in the reflection of solar radiation, as more heat is absorbed by the gases instead of being reflected back into space.
Troposphere does not absorb solar radiation. All other layers do not absorb.
UV
The solar radiation can be divided into many parts. The UV radiation part of it helps to form the ozone.
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
NONE

About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
