The cryosphere encompasses the frozen parts of Earth, including glaciers and ice sheets, sea ice, and any other frozen body of water. This is a measurement of the solar irradiation that would reach a solar system whose angle is fixed and set to the optimum tilt angle for its location. As the cloud cover used in the case study is an hourly data collected only at the time indicated ( National Solar Radiation Data Base, 2001 ), namely, at the beginning of each hour, it . Additionally, a listing of solar spectral irradiance, smoothed over the detailed Fraunhofer structure, is presented for engineering use.
