The finding that solar activity was approximately the same in cycles 14 and 24 applies to all solar outputs that have, in the past, been proposed as a potential cause of terrestrial climate change and includes total solar irradiance, cosmic ray fluxes, spectral UV irradiance, solar wind speed and/or density, heliospheric magnetic field and its ...

The primary energy input is the global light irradiance in the plane of the solar arrays, and this in turn is a combination of the direct and the diffuse radiation. [ 1 ] The performance is measured by PV monitoring systems, which include a data logging device and often also a weather measurement device (on-site device or an independent weather ...
Obtain daily measurements of solar spectral irradiance between 0.3 and 2 μm with a spectral resolution of at least 1/30, an accuracy of 0.03%, and long-term repeatability of better than 0.01%/yr. To improve the understanding of how and why solar irradiance varies, estimate past and future solar behavior, and investigate climate responses.
The PI (or photosynthesis-irradiance) curve is a graphical representation of the empirical relationship between solar irradiance and photosynthesis. A derivation of the Michaelis–Menten curve, it shows the generally positive correlation between light intensity and photosynthetic rate. It is a plot of photosynthetic rate as a function of light ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
In particular, at Earth temperatures, and all else being equal, greater tilt warms the poles and thus reduces polar ice coverage, while lesser tilt cools the poles and thus increases polar ice coverage. [4] This graph shows a very simple approximation of relative solar-noon heating on Earth as a function of season and latitude, as resulting ...
