What are the factors that affect the amount of solar radiation?
In total seven influences on solar radiation have been identified:
- Solar elevation. Where the sun sits in the sky determines the level of UV radiation reaching us.
- Ozone.
- Cloud cover.
- Ground surface reflectivity.
- Altitude.
- Aerosols and pollutants.
- Direct and diffuse UV.
What factors affect the amount of solar energy that reaches the earth’s surface Brainly?
Weather, Location and Time of year.
Which factor does not affect the amount of solar radiation received at the surface of the earth?
longtitude
Is the amount of radiation emitted by the sun a constant?
The electromagnetic radiation emitted by the sun covers a very large range of wavelengths, from radiowaves through the infrared, visible and ultraviolet to X-rays and gamma rays. The total radiation emitted by the sun in unit time remains practically constant.
Which region receives the highest solar radiation?
The equator
Is solar flux constant?
Role of the Atmosphere Solar flux just outside the Earth’s atmosphere is referred to as the ‘solar constant’ and has a value of approximately 1373 W m−2. Reflectance, scattering, and absorption of light in the atmosphere can reduce this amount by 15–80% before reaching the Earth’s surface.
What is the formula for energy flux?
Energy flux is the rate of transfer of energy through a surface. The quantity is defined in two different ways, depending on the context: Total rate of energy transfer (not per unit area); SI units: W = J⋅s−1.
How do you calculate the flux of the sun?
flux = luminosity/4*pi*distance^2 luminosity of the sun = 3.8 x 10^26 watts distance from earth to sun = 1 AU or 1.5 x 10^11 meters I keep getting 1343 w/m^2 but i have … Solar flux just outside the Earth’s atmosphere is referred to as the ‘solar …
Why do deserts have high albedo?
Deserts, ice and clouds, however, have high albedos; they reflect a large portion of the sun’s energy. Surface conditions (moisture, surface vegetation, snow cover etc) strongly affect albedo and high quality ground truth data is necessary in support of satellite measurements.
