MODULE 2.3 METEOROLOGY: SOLAR RADIATION Flashcards

1
Q

It refers to the energy that is emitted by
the sun in the form of electromagnetic waves. This energy travels through space and reaches the Earth’s atmosphere, where it can be absorbed or reflected by various substances, such as the Earth’s surface,
clouds, and gases in the atmosphere.

Q

It refers to the amount of solar radiation that is received by a surface, such as the Earth’s surface or the surface of a solar panel, per
unit area (watts/sq.m). It is typically measured in watts per square meter.

*Sun path & solar declination

15
Q

What are the atmospheric effects?

A

*Direct Normal Irradiance
*Diffuse Irradiance
*Albedo Irradiance
*Global Horizontal Irradiance
*Global In-Plane Irradiance

16
Q

It is a radiation from the sun that
reaches the earth without scattering.

A

Direct Normal Irradiance

17
Q

It is a direct or diffuse radiation
reflected from the soil or nearby surfaces (snow, lakes, etc.)

A

Albedo Irradiance

18
Q

It is a radiation that is scattered by the
atmosphere, clouds, and may arrive from all directions.

A

Diffuse Irradiance

19
Q

It is the total amount of shortwave radiation received from above by horizontal surface. It includes both Direct Normal Irradiance and Diffuse Horizontal Irradiance.

A

Global Horizontal Irradiance

20
Q

It is the total amount of radiation received from above by an inclined surface.

A

Global In-Plane Irradiance

21
Q

What are the instruments use in measuring radiations?

A

*Pyranometer
*Pyrheliometer
*Spectroradiometer

22
Q

It is a device that can be used to measure both beam radiation and diffuse
radiation.

A

Pyranometer

23
Q

It is a device used for measuring direct
beam radiation at normal incidence.

A

Pyrheliometer

24
Q

It measures solar radiation spectrally
resolved.

A

Spectroradiometer

25
Q

What are the measurement techniques?

A

Beam Radiation (IB)
Diffuse Radiation (ID)
Total Radiation (IT)

26
Q

It is a direct sunlight and doesn’t scatters.

A

Beam Radiation

27
Q

It is also known as global radiation.

A

Total Radiation

27
Q

It is where solar radiation scattered by
aerosols, dust and molecules.

A

Diffuse Radiation

28
Q

This instrument is use in weather stations, scientific research etc.

A

Pyranometer

29
Q

It measures intensity of sunlight and solar radiation and also is a “special lights” instrument.

A

Pyrheliometer

30
Q

It measures atmospheric composition, aerosols content (absorption & scattering of solar energy)

A

31
Q

It measures per area and also known the “total solar irradiance”

A

Total Radiation

32
Q

Formula of Total Irradiance

A

IT = IB + ID
