Solar irradiance
From Wikipedia, the free encyclopedia
Solar irradiance may refer to:
- Sunlight, including light, infrared, ultraviolet, and any other wavelength of electromagnetic radiation the Sun gives off
- Insolation, solar radiation energy received on a given surface area during a given time
- Direct insolation, solar irradiance which reaches a location on Earth after absorption and scattering in the atmosphere
- Total solar irradiance (TSI), the amount of solar radiative energy incident on the Earth's upper atmosphere
[edit] See also
- Solar Irradiance Monitor
- Solar activity and irradiance measurement
- Solar constant, the amount of solar electromagnetic radiation per square unit area at a distance of one astronomical unit from the Sun
- Pyranometer, measures broadband solar irradiance on a planar surface
- Pyrheliometer, measures solar irradiance directly
- Picard (satellite), measures solar irradiance, the solar diameter, probes the Sun's interior with helioseismology
- Sunflecks, brief increases in solar irradiance that occur in forest understories when sunlight is able to directly reach the ground. They are caused by either wind moving branches in the canopy or as the sun moves during the day.
