Routine measurements of the broadband direct normal irradiance (DNI), i.e. beam irradiance at normal incidence, by means of pyrheliometers or equivalent pyranometric systems include the irradiance originating from within the extent of the solar disc (DNIS) and that from a larger circumsolar region, called the circumsolar normal irradiance (CSNI). Such instruments have equivalent aperture half-angles between 2.5° and 5° which are one order of magnitude greater than the angular radius of the solar disc. The equivalent aperture half-angles of the concentrated solar powered systems are greater than the angular radius of the solar disc, but smaller than that of the measuring systems. Therefore, information on the CSNI should be provided for an i...
