Flashcards

Short Wavelength Radiation

Radiation with shorter wavelengths, such as ultraviolet (UV) light, is emitted from the sun in bursts and is not constant.

Visible Light Radiation

Radiation in the visible light spectrum is emitted steadily and constantly from the sun. It's what allows us to see!

Infrared Radiation

Radiation with longer infrared wavelengths is emitted in varying amounts. It contributes significantly to the Earth's energy balance.

Extreme Ultraviolet (EUV) Radiation

Radiation in the extreme ultraviolet (EUV) range is emitted in bursts and has the most significant variation. It's heavily influenced by solar activity.

Total Solar Irradiance (TSI)

Total Solar Irradiance (TSI) is the total amount of solar radiation that reaches the Earth's atmosphere. It's a measurement of all types of solar radiation.
