Integrating nephelometer, truncation error

Real-world integrating nephelometers integrate scattered light within a large but limited sub-range of the ideal angular range of 0 ° to 180 °. The imperfect integration is referred to as the trunction error. This error increases with the steepness of the volume scattering function. It is relatively small for atmopsheric applications (Abu-Rahmah A et al 2006, Marshall J et al 2005, Moosmuller H and Arnott 2003, Anderson TL et al 1996, Mulholland GW and Bryner 1994, Sloane CS et al 1991, Ensor DS and Waggoner 1970), but is quite significant for natural waters, which limits applications of integrating nephelometers in aquatic research (Jonasz M and Fournier 2007 (pp. 186-191).
