What else can I help you with?
What is the percentage of solar radiation reflected from a surface?
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
An object with high abedo apears brighter then an object with low albedo?
Yes, that is correct. An object with high albedo reflects more incoming solar radiation back into space, which makes it appear brighter. On the other hand, an object with low albedo absorbs more of the incoming solar radiation, hence appearing darker.
What surfaces has the highest albedo?
Surfaces covered in fresh snow or ice typically have the highest albedo, reflecting about 80-90% of incoming solar radiation. This high reflectivity helps to keep these areas cooler by reducing the amount of solar energy absorbed.
Do clouds reflect sun's radiation?
Yes, clouds can reflect incoming solar radiation due to their high albedo, which is the measure of how much sunlight is reflected off a surface. This reflection can have a cooling effect on the Earth's surface by reducing the amount of solar radiation that reaches it.
What are some example of high albedo?
Fresh snow, ice, and white sand are examples of surfaces with high albedo. These surfaces reflect a large percentage of incoming solar radiation back into space, resulting in a cooling effect on the surrounding environment.
How does albedo affect the behavior of solar radiation reaching earths surface?
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.
What are the differences in the amount of solar radiation absorbed by surfaces with high versus low albedo?
Surfaces with high albedo reflect more solar radiation, while surfaces with low albedo absorb more solar radiation.
What are the differences in the amount of solar radiation absorbed and reflected between surfaces with low albedo and surfaces with high albedo?
Surfaces with low albedo absorb more solar radiation and reflect less, while surfaces with high albedo reflect more solar radiation and absorb less.
If earths albedo was higher but earth was farther from the sun could the earth have the same temperature?
No, if Earth's albedo was higher and it was farther from the sun, it would receive less solar radiation, leading to cooler temperatures overall. Albedo affects how much incoming solar radiation is reflected back into space, but distance from the sun determines how much solar radiation reaches Earth in the first place.
What is the percentage of solar radiation reflected from a surface?
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
How do ice and water on the ground impact the absorption and reflection of incoming solar radiation?
Ice and water on the ground impact the absorption and reflection of incoming solar radiation by changing the surface albedo. Ice and snow have high albedo, meaning they reflect more sunlight back into space, while water has a lower albedo and absorbs more sunlight. This affects the amount of solar energy that is absorbed by the Earth's surface, leading to changes in temperature and climate.
The albedo of the earth's surface is the fraction of solar radiation that is?
The albedo of the Earth's surface is the fraction of solar radiation that is reflected back into space. It is a measure of how reflective a surface is, with higher albedo values indicating more reflection and less absorption of sunlight by the surface. Land surfaces, ice, and clouds generally have higher albedo values, while oceans and forests have lower albedo values.
What has the author G Louis Smith written?

Louis Smith has written: 'Atlas of albedo and absorbed solar radiation derived from Nimbus 7 earth radiation budget data set, November 1978 to October 1985' -- subject(s): Albedo, Charts, diagrams, Heat budget (Geophysics), Measurement, Measurrement, Nimbus (Artificial satellite), Terrestrial radiation 'Atlas of albedo and absorbed solar radiation derived from Nimubs 6 earth radiation budget data set - July 1975 to May 1978' -- subject(s): Albedo, Earth radiation budget, Solar radiation
What is the importance of albedo?
The albedo effect reflects the sun's radiation helping to slow the effects of global warming (like sea ice, white ice caps and glaciers). If (or when) these melt, then the reflection will stop and the warming will speed up!
An object with high abedo apears brighter then an object with low albedo?
Yes, that is correct. An object with high albedo reflects more incoming solar radiation back into space, which makes it appear brighter. On the other hand, an object with low albedo absorbs more of the incoming solar radiation, hence appearing darker.
Same and differences of albedo and insolation?
The albedo effect is how a darker material gets hotter faster than a lighter material. Insolation is the solar radiation from the sun.
How does changing a planet's albedo change a planet's temperature?
If you increase the albedo, more solar radiation will be reflected back into space and so the temperature will be lowered.
