SRML Glossary "G" Special thanks to NREL We'd like to thank the National Renewable Energy Laboratory for making available to us their glossary, which is the basis of ours. We've edited and reformatted it, and linked it to our Web pages, and we'll continue to add our own specialized terms, illustrations, and examples. Please note that the Solar Radiation Monitoring Laboratory takes full responsibility for any inaccuracies that may occur.

| 1,000,000,000
(or 109) Watts. This unit rose to public
prominence in the 1985 motion picture Back to the Future in which
1.21 gigawatts of power were required for the time-travelling vehicle.

| Total solar
radiation; the sum of direct,
diffuse, and ground- reflected radiation; however, because ground reflected radiation is usually insignificant compared to direct and diffuse, for all practical purposes global radiation is said to be the sum of direct and diffuse radiation only.

| The warming
of the Earth by the atmosphere because of water vapor and gases such as
carbon dioxide, which absorb and emit infrared
radiation, or heat. Thus, the high-energy photons such as light and
ultraviolet radiation are passed
through the atmosphere to the Earth, which tends to absorb them and emit
lower-energy photons which are then captured in the atmosphere and partially
sent back to Earth. As the presence of infrared absorbers rises in the atmosphere,
the more solar energy is retained at heat in the atmosphere and on the surface
of the Earth. Because glass also passes light and tends to absorb and reflect
heat, this effect is compared to that of a greenhouse.
