  • Chapter 2 is an introduction to the solar components, effects of the earth’s orbit on solar radiation at the top of the atmosphere, the spectral distribution of solar irradiance, and the variability of the “solar constant” when measured from space.
  • Chapter 2 is an introduction to the solar components, effects of the earth’s orbit on solar radiation at the top of the atmosphere, the spectral distribution of solar irradiance, and the variability of the “solar constant” when measured from space.
  • The handbook also addresses the question, “How much accuracy can you afford?” by describing pyrheliometer and pyranometer calibrations and measurement uncertainties.
  • Chapter 3 presents details of radiometer design (pyranometer and pyrheliometer), performance standards, and related topics.
  • Chapter 6 describes the key aspects of applying solar resource data to a CSP project.
  • Chapter 6 also describes in detail the use of GIS analysis, short-term data to estimate longer term performance, and atmospheric effects of importance to DNI.Note: Modeling Clear sky DNI requires accurate determinations of aerosols!
