	Encyclopedia: Electromagnetic radiation
		The physics of electromagnetic radiation is electrodynamics, a subfield of electromagnetism.
		Generally, EM radiation is classified by wavelength into electrical energy, radio, microwave, infrared, the visible region we perceive as light, ultraviolet, X-rays and gamma rays.
		EM radiation with a wavelength between 400 nm and 700 nm is detected by the human eye and perceived as visible light.

	Radiation and Atmospheric
		Shortwave radiation is computed as a function of specific humidity, cloud cover, surface albedo, and solar zenith angle.
		For clear sky conditions, shortwave radiation focuses on aerosol scattering and the effects of the absorption by water vapor, ozone, oxygen, carbon monoxide, methane, and nitrous oxide using line parameters of Rothman et al.
		Shortwave radiation in the cloudy scheme focuses on the absorption and scattering properties of cloud droplets.

	EO Library: Clouds & Radiation Fact Sheet
		Visible radiation and radiation with shorter wavelengths, such as ultraviolet radiation are labeled "shortwave." Both the amount of energy and the wavelengths at which energy is emitted by any system are controlled by the average temperature of the system's radiating surfaces, plus the emission properties.
		Unlike solar radiation, which is mostly at wavelengths visible to the human eye, the Earth's longwave radiation is mostly at infrared wavelengths, which are invisible to the human eye.
		However, a significant fraction of the longwave radiation emitted by the surface is absorbed by trace gases in the air.

		Radiating bodies have typical portions of the electromagnetic spectrum in which their radiation isconcentrated.
		Radiant energy may be originated in a body orreflected from another body (in which case it may be refracted or otherwise modified).
		Radiant energy produced in the sun is a result of nuclear fusion and, ultimately, interacts with the earth'satmosphere and surface.

	Solar Radiation as a Factor in Arctic Weather and Climate
		Since solar radiation represents almost all the energy available to the earth, accounting for solar radiation and how it interacts with the atmosphere and the earth's surface is fundamental to understanding the earth's energy budget.
		About 50 percent of solar (or shortwave) radiation is reflected back into space, while the remaining shortwave radiation at the top of the atmosphere is absorbed by the earth's surface and re-radiated as thermal infrared (or longwave) radiation.
		The intensity of solar radiation striking a horizontal surface is measured by a pyranometer.

	Lab Instructions: The Earth's Radiation Budget (Site not responding. Last check: 2007-10-16)
		When visible radiation from the Sun reaches the Earth and the sky is clear, some of it is reflected or scattered directly back into space as shortwave radiation (the percent reflected is known as albedo), and some of it is absorbed by the Earth.
		However, due to the curvature of the earth, this radiation is incident on larger and larger areas as the latitude increases.
		The angle of incoming solar radiation varies both diurnally and seasonally - for example, the sun is directly overhead on the equator at noon on an equinox, but is still at an angle of 0 degrees at sunrise and sunset on the equator at an equinox.

	Earth Radiation Budget
		The Earth Radiation Budget is the balance between incoming energy from the sun and the outgoing longwave (thermal) and reflected shortwave energy from the Earth.
		The spectrum of the solar radiation received at the top of the atmosphere is well approximated by the spectrum of a flbody having a surface temperature of about 6000K.
		The downward shortwave radiation may be reflected to the space absorbed in the atmosphere and absorbed at the ground.

	Apogee Instruments Inc: Pyranometer Sensor
		The term cosine or Lambertian response is the decrease in radiation intensity on a flat surface as the angle of the surface decreases from perpendicular (normal or 0 degrees zenith angle).
		The biggest error in measuring shortwave radiation on an automated weather station is usually caused by occlusion of the lens of a sensor by dust or water residue.
		All silicon Pyranometers sub-sample the shortwave radiation spectrum (from 350-1000 nm), and are calibrated to predict all of the solar radiation (from 280 to 2800 nm).

	buoy-sw.html
		Two years of surface shortwave flux data, from five buoys in the subtropical North Atlantic Ocean during the Subduction Experiment, were used to examine shortwave absorption in the atmosphere, and its partitioning between the clear and cloudy sky.
		Given the Subduction Experiment's unique and potentially valuable record of surface shortwave observations, the purpose of this study is to analyze and exploit these data in order to address a number of important questions regarding the measurement, modeling, and understanding of shortwave radiation in our climate system.
		The shortwave radiation data from the five buoys was then closely checked for consistency among the five buoys and with the reference sensor and also for any evidence that radio frequency energy from the satellite transmitters was exciting the radiometers.

	GFS Radiative Transfer, Page 3 (Site not responding. Last check: 2007-10-16)
		The scattering, reflection, and absorption characteristics of the atmosphere with respect to shortwave radiation transfer in the GFS are determined hourly in each layer, for both downward and upward solar fluxes (after reflection by clouds and the earth surface).
		While the full shortwave radiation calculation is only done hourly, the effect of changes in the solar zenith angle (the height of the sun in the sky) at each grid point is taken into account every time step (3 min.).
		The violet box encompasses the range of the model UV bands, the green box is the model visible spectrum band, and the red box is the model near infrared band, which extends beyond the end of the graphic to 10 µm.

	Assessing Ocean Buoy Shortwave Observations using Clear-Sky Model Calculations
		The confidence in the representation of clear-sky shortwave radiation by the theoretical radiative transfer models is supported by studies such as Cess et al.
		Shortwave samples were then discarded if the ratio of the observed change and the expected change in SW differed from 1.0 by 50% or more.
		While this case demonstrates the influence of aerosols on the evolution and simulation of the shortwave, it appears that over the course of the deployment the model-data bias is rather small due to the cancellation between periods of low (underspecified) and high (overspecified) aerosol.

	Radiation Calculations (RADCTL)
		The source of all imbalance in radiation is the shortwave radiation package, RADCSW, because it is computed only in half the grid points (the ones in daylight) at any given time.
		The regularity of this pattern of imbalance suggested a straightforward scheme for correcting a large percentage of the shortwave radiation load imbalance.
		Before shortwave radiation is invoked in a time step, every other point in a latitude (an east-west row of points) is exchanged between processors, decomposing that row in such a way that, after the exchange, each processor has almost the same number of day and night points.

		The term "reflected shortwave radiation" refers to the sum total of all the shortwave electromagnetic energy, or sunlight at wavelengths ranging from 0.3 to 5 micrometers, that escapes from the top of the Earth's atmosphere back into space.
		The image above is a false-color map showing the amount of shortwave energy (in Watts per square meter) that was reflected by the Earth system for the given month(s).
		Notice that regions that are typically cloudy tend to reflect more shortwave energy, while the land surface reflects less than clouds, and the ocean reflects less than the land.

	Appendix A
		= total net radiation, LE = latent (energy due to evaporation) heat flux, H = sensible (convective) heat flux, and G = downward heat flux due to conduction of the surface.
		Similarly, the surface itself radiates longwave energy upward as a function of surface temperature.
		The net radiation absorbed at the surface is then channeled into the three fluxes given by LE, H, and G. The sum of these three fluxes must remain constant, so that an increase in one necessarily decreases one or both of the other two.
