What is a pyranometer?

A pyranometer measures direct and diffuse solar radiation.


What determines the amount of solar energy absorbed by the earth?

Every location on Earth receives sunlight at least part of the year. The amount of solar radiation that reaches any one "spot" on the Earth's surface varies according to these factors:Geographic locationTime of daySeasonLocal landscapeLocal weather.Diffuse and Direct Solar RadiationAs sunlight passes through the atmosphere, some of it is absorbed, scattered, and reflected by the following: Air moleculesWater vaporCloudsDustPollutantsForest firesVolcanoes.This is called diffuse solar radiation. The solar radiation that reaches the Earth's surface without being diffused is called direct beam solar radiation. The sum of the diffuse and direct solar radiation is called global solar radiation. Atmospheric conditions can reduce direct beam radiation by 10% on clear, dry days and by 100% during thick, cloudy days.


What is solarimeter?

an instrument used to measure the flux of solar radiation through a surface.


What Is terrestrial radiation and How does it differ from solar radiation?

They are essentially the same thing. Solar radiation from the sun is made up of two components: (1) direct solar raidation; and (2) diffuse solar radiation. Global radiation refers to the sum of direct and diffuse fractions.


The light from the sun is called?

Heat from the sun is called Solar Radiation, so the answer is SOLAR RADIATION


Intercepted solar radiation is called?

Insolation is intercepted solar radiation.


What is difference between direct and diffuse solar radiation?

— Direct solar beam - have specific directions, from sun to earth's surfaces - 17 % — Diffuse radiation from clouds - 21 % and from sky - 7 % (comes from all directions of the hemisphere) — Reflectivity is the reflected fraction of incident radiation at specific wavelength. — Albedo (α) is the reflection over the entire solar spectrum (the whole range of wavelengths). Examples: — Snow is very reflective to visible and completely reflective to infrared radiation. Albedo is 1 or 100 %. In leaves, there is less absorption and more reflection for the green light in the visible spectrum, compared to blue and red light, where reflection is much less, causing the leaves to be appeared as green.


What is incident radiation?

Radiation is a general term for the energy transmitted through space.Incident radiation is a term used when referring to the radiation hitting a specific surface. For instance, the incident radiation for a solar panel is the total amount of radiation hitting the surface of the solar panel. This is in contrast to direct beam radiation which refers to only that radiation which arrives in a strait line from the sun. (It differs in that total incident radiation includes additionally the component of diffuse radiation.)


Another word for Incoming Solar Radiation?

incoming solar radiation = insolation


When is solar radiation most intense?

How does volcanic ash in Earth's atmosphere affect solar radiation?
