Solar Radiation And Greenhouse Effect

The greenhouse effect causes some of this energy to be waylaid in the atmosphere absorbed and released by greenhouse gases.

Solar radiation and greenhouse effect.

Climate climate solar radiation and temperature. The greenhouse effect is the process by which the atmosphere of a planet lets solar radiation from the sun pass but instead prevents or hinders the exit of thermal energy from the planet. It is in part a natural process. Of those gases known as greenhouse gases water vapor has the largest effect.

They are subject to many influences including those of the atmosphere ocean and land and are modified by them. While not an argument against solar radiation management per se this is an argument against reliance on climate engineering to the exclusion of greenhouse gas reduction. However earth s greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. For more than 40 years satellites have observed the sun s energy output which has gone up or down by less than 0 1 percent during that period.

Air temperatures have their origin in the absorption of radiant energy from the sun. Warming from increased levels of human produced greenhouse gases is actually many times stronger than any effects due to recent variations in solar activity. Solar radiation is often called shortwave radiation. Photovoltaic greenhouses became popular in many countries for growing crops and at the same time generating electricity mainly for own usage to control the air temperature inside the greenhouse.

Adding more greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere. As variation of solar radiation is the single most important factor affecting climate it is considered here first. Greenhouse effect a warming of earth s surface and troposphere the lowest layer of the atmosphere caused by the presence of water vapor carbon dioxide methane and certain other gases in the air. To get the energy back in balance the surface of the earth has to warm up so that it will emit more infrared energy some of which will leave the atmosphere and compensate for the effect of the added greenhouse gases.

The greenhouse effect occurs when earth s atmosphere traps solar radiation because of the presence of certain gases which causes temperatures to rise. Without the greenhouse effect earth s temperature would be below freezing. It is called the greenhouse effect because of the similarity with the operation of the greenhouses. Radiatively active gases i e greenhouse gases in a planet s atmosphere radiate energy in all directions part of this radiation is directed towards the surface warming it.
