Radiosonde - an instrument package that moves through the atmosphere, usually attached to a balloon, and transmits data over a radio frequency. The amount of change is a function of the scattering particles and the wavelengths of light. Rayleigh scattering explains the blue sky. The RCC controls all data acquisition from the reference radiometers and those under calbration, displays several color-coded fields representing the present sky condition and instrument performance, builds an instrument calibration database, and generates the final calibration report. Renewable Energy - there is no formal definition for this term.
Typical usage defines it as any energy source that is replenished at least as fast as it is used .
Standard examples are solar, wind, hydroelectric, and biomass products. Receiver - a device that receives solar energy and converts it to useful energy forms. The following figure from Shining On illustrates several types of receivers. Reflectance - the fraction or percent of a particular frequency or wavelength of electromagnetic radiation that is reflected from the surface of a substance without being absorbed or transmitted. Refraction - the bending of electromagnetic radiation by its passage through a medium of a high refractive index.
