- About 51% of solar energy reaching the earth is absorbed by the Earth's surface. 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% (Source: NASA.)

- About 29 percent of the solar energy that arrives at the top of the atmosphere is reflected back to space by clouds, atmospheric particles, or bright ground surfaces like sea ice and snow. This energy plays no role in Earth’s climate system. About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface.

- Abstract The fraction of the incoming solar energy scattered by Earth back to space is referred to as the. planetary albedo. This reﬂected energy is a fundamental component of the Earth’s energy balance, and the. processes that govern its magnitude, distribution, and variability shape Earth’s climate and climate change.

- The atmosphere directly absorbs about 23% of incoming sunlight, and the remaining energy is transferred from the Earth’s surface by evaporation (25%), convection (5%), and thermal infrared radiation (a net of 5-6%).

Water Main articles: Hydrology and Water distribution on Earth. Water covers 71% of the Earth's surface; the oceans contain 96.5% of the Earth's water. The Antarctic ice sheet, which contains 61% of all fresh water on Earth, is visible at the bottom. Condensed atmospheric water can be seen as clouds, contributing to the Earth's albedo.

Introduction Much of this radiation is absorbed by the Earth's surface and re-emitted as invisible heat rays. Just as a hot pavement radiates heat as it is warmed by the sun, the Earth's surface radiates heat back to the atmosphere. If incoming solar radiation is 100 units: 16 units are absorbed by dust, water and ozone;

- Some 30 percent of all incoming solar radiation never makes it to ground level. In space the sun is always shining, the tilt of the Earth doesn't prevent the collection of power and there’s no atmosphere to reduce the intensity of the sun’s rays. This makes putting solar panels into space a tempting possibility.

Water distribution on Earth Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 70% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot.

Marine life How much of the Earth is water? 1  The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water. 2  Less than 1 percent of the Earth's water is fresh water, and 2-3 percent is contained in glaciers and ice caps.  The oceans contain 99 percent of the living space on the planet.

Part 2: Solar Energy Reaching The Earthâs Surface The fraction of the total solar radiant energy reflected back to space from clouds, scattering and reflection from the Earth’s surface is called the albedo of the Earth-atmosphere system and is roughly 0.3 for the Earth as a whole.igure 2.1: The Sun's rays incident on the Earth. I0 = irradiance on a plane perpendicular to the Sun's rays. The solar constant (I SC) is the average radiation intensity falling on an imaginary surface, perpendicular to the Sun’s rays and at the edge of the Earth’s atmosphere (figure 2.1).

Probing the Role of the Sun In an Era of Global Warming In its youth, for example, billions of years ago, the Sun put out only about 70 percent as much energy as it does now — it’s only thanks to the greenhouse gases thought to have blanketed the planet at that time that all the Earth’s water didn’t turn to solid ice.

- Yet this amount of energy is enormous. The sun provides more energy in an hour than the United States can use in a year! About 30 percent of the radiant energy that reaches the Earth is reflected back into space. About half of the radiant energy is absorbed by land and oceans.

- Direct sunlight striking earth’s surface provides energy at a rate. of about 1000 watts per square meter of surface area. Suppose that the ground in. a certain location (perhaps the mountains in springtime) is covered with snow to a. depth of two meters, and that the snow is half ice and half air.

What percentage of the Earth's land is above the equator? There is an unequal distribution of land and water between the two hemispheres. The Southern Hemisphere has less land and more water. The Northern hemisphere is about 60.7% water and 39.3% land. The Southern hemisphere is about 80.9% water and 19.1% land. 63.7% of Earth's land mass is above the Equator.

What percent of Earth is water? Scientists calculate that the total mass of the oceans on Earth is 1.35 x 1018 metric tonnes, which is 1/4400 the total mass of the Earth. In other words, while the oceans cover 71% of the Earth's surface, they only account for 0.02% of our planet's total mass. The origin of water on the Earth's surface, as well as the fact that it has more water than any other rocky planet in the Solar System, are two of long-standing mysteries concerning our planet.

Solar Energy, Albedo, and the Polar Regions Snow, ice, and clouds have high albedos (typically from 0.7 to 0.9) and reflect more energy than they absorb. Earth’s average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space and 70 percent is absorbed. A sensor aboard NASA’s Terra satellite is now collecting detailed measurements of how much sunlight the earth’s surface reflects back up into the atmosphere.

How much sunlight hits the Earth? About 50% of this energy makes it to the Earth’s. surface, the rest is reﬂected by clouds and aerosols, or is. absorbed in the atmosphere. This means 700 J/(m2 sec) is available at the Earth’s. surface…. …this already takes in consideration average weather. conditions and clouds.

- The ocean holds about 97 percent of the Earth's water; the remaining three percent is distributed in many different places, including glaciers and ice, below the ground, in rivers and lakes, and in the atmosphere.

- NASA publications confirm (Science 308, 1431-1435) that Earth absorbs more energy from the Sun that it is able to reflect to space - about 0.85 MegaWatt per square kilometer more. Pollution increases daily and Solar activity is on the increase until 2012.

Energy: The Driver of Climate In the following investigation you will learn about Earth’s energy budget and the processes that balance the incoming solar radiation and the outgoing terrestrial radiation. To balance the absorbed incoming energy, Earth must on average, emit the same amount of radiation to space.

- Earth reflects an average of 36 percent of the insolation. The percent of reflectivity of all wavelengths on a surface is known as its albedo. Earth’s average albedo is from 36 to 43 percent. That is, Earth reflects 36 to 43 percent of insolation back into space. In calculating the albedo of Earth, the assumption is made that the average cloudiness over Earth is 52 percent.

- The amount of sunlight the Earth absorbs depends on the reflectivness of the atmosphere and the ground surface. This satellite map shows the amount of solar radiation (watts per square meter) reflected during September 2008.
