In the Stratosphere Which of the Following Increases Earth's Albedo

From Latin albedo whiteness is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0 corresponding to a black body that absorbs all incident radiation to 1 corresponding to a body that reflects all incident radiation. If the amount of cloud cover increases in response to greenhouse warming this will __________ Earths albedo and promote __________.

The importance of sulfur in the Earths atmosphere and environment is well established.

. Albedo æ l ˈ b iː d oʊ. As a result its albedo will decrease and the earth will absorb more energy. Earth Sciences questions and answers.

This global picture of reflectivity also called albedo. Some black carbon settles on the surface of the ice which reduces albedo. 76 An increase in the Earths albedo would A have no effect on the planets temperature because insolation is constant B cool the planet C warm the planet Answer.

The range of albedo on the Earths surface can be as little as 3 003 for water and as high as 95 095 for fresh snow cover. A increasing carbon dioxide concentrations Select b retreating decreasing glaciers worldwide Select 1 c volcanic eruption Select d increased activity of the biological pump Select e decreased cloud cover. This would lead to a global temperature reduction equivalent to decreasing CO 2 emissions by 6575 kg m 2 010001 15 10 12 m 2 10 10 13 kg11 10 13 kg or 100110 Gt CO 2.

Albedo also changes due to human interaction. The geo-engineers have suggested plan of action to increase the Earths Albedo are given below. The Little Ice Age ended about 1849 and warming started.

Aerosol sulfate is known to alter atmospheric radiative processes due to its role in increasing the Earths albedo and as a cloud condensation nucleus and is a component of the sulfur cycle and environmental acidification. What would you rather walk on in bare feet asphalt albedo 5-10 or concrete albedo 15-25. B B cool the planet 77 The greatest annual temperature ranges are characteristic of places like A Los Angeles and London B Verkhoyansk and Oymyakon C Los Angeles and.

For UPSC 2022 follow BYJUS. For this question assume that albedo effects dominate the temperature response The passage of insolation through the atmosphere is an example of _____. Burning wood and fossil fuels adds black carbon to the atmosphere.

Sulphate aerosols reduce the amount of absorbed of solar radiation absorbed by Earths surface in two ways. Answer 1 of 6. Weve been warming since 1850.

Memorize flashcards and build a practice test to quiz yourself before your exam. Using satellite measurements accumulated since the late 1970s scientists estimate Earths average albedo is about about 030. Albedo is the percentage of solar radiation reflected by a given surface.

Passage of shortwave and longwave energy through atmosphere or water is an example of. For us we are being told OUR CO2 unbalanced the natural 280 ppm that had been for about 800000 years. Bis located at a band.

The asphalt will usually be hotter in large part because more sunlight is absorbed by the surface. B The higher the albedo the more light the surface reflects. For example if the albedo of a surface is 25 then 25 of the sunlight falling on it is reflected back toward the.

An interesting characteristic of this layer is that heat increases with altitude due to ultraviolet light being absorbed from the. Albedo and absorption are counterparts of the reflective properties of a surface. Albedo and Global Warming.

Start studying the chapter 10 - astronomy flashcards containing study terms like 1 Which of the following correctly describes the meaning of albedo. Forests have lower albedo than topsoil. 16Most of the outgoing terrestrial radiation at the top of the atmosphere are emitted from.

1 the aerosols are reflective. An albedo increase of 01 in urban areas corresponds to increasing the albedo to roofs by an average of 025 and the albedo of pavements by 015. One of those aerosols sulphate aerosols increases Earths albedo by making the atmosphere more reflective.

The maps above show how the reflectivity of Earththe amount of sunlight reflected back into spacechanged between March 1 2000 and December 31 2011. Surface albedo is defined as the ratio of radiosity J e to the. Estimates of Earths albedo have remained largely unchanged from the value of 030 deduced from earliest measurement first from the Explorer-7 satellite observations in 1959 Kandel and Viollier 2010.

How do each of the following processes affect Earths planetary top-of-the-atmosphere albedo. Chemical reactions in the atmosphere involving SO 2 can produce sulphate aerosols. If the Earths average temperature increases due to the enhanced greenhouse effect the surface covered by snow and ice will fall and the earths surface will reflect less radiation.

The stratosphere is the second major layer in the Earths atmosphereIt is located above the troposphere and below the mesosphere. Early to mid 19th century CO2 readings showed many levels above 400 ppm. Read to know how it affects Climate Change for IAS Exam.

There are a couple of ideas for making the atmosphere reflect more sunlight including brightening clouds and adding aerosols tiny particles either solids or liquids that stay suspended in the atmosphere for a relatively long period of time. The idea is to reflect some fraction of solar radiation away from earth thus counteracting the extra heat trapped by GHGs. Athe atmosphere BEarths surface 17The atmospheric window.

The temperature of the Earths atmosphere and oceans will rise even more. Which of the following has the highest albedo. Ais a local phenomenon similar to the ozone hole that opens over Antarctica in winter.

There are numerous proposed mechanisms as Bala 2009 explains. This value was later confirmed from the Nimbus satellite measurements by Vonder Haar and Suomi and Jacobowitz et al. The second major way to actively lower global temperature is to increase the earths albedo or reflectivity.

Spraying of sulphate aerosols into. A The lower the albedo the more light the surface reflects and the less it absorbs.
