It is not technically correct to say the light is "reflected" by the particles; more accurate would be "scattered". Light scattering is a phenomenon that occurs because the wavelength of light is on the same order as the particle dimensions, and includes light refraction, diffraction and reflection.

Inaccurate

edit

This article on nephelometers is inaccurate and doesn't reflect what the instruments measure or how they are used by the atmospheric community. Since when is there a "NOAA" facility on Cheju-do? There's an SNU facility, nothing else. Nephs are calibrated to CO2, which has a known scattering coefficient not Arizona road dust or synthetic particles. They don't measure particle density. The instrument measures a scattering coefficient. I suggest the article be edited o even deleted. Start with the TSI instrument manual and then move on to field measurements and how the data is used. Note that the instrument is fairly insensitive to super micron particles so the graph with particles sizes and types isn't relevant. Think instead of Aitken and accumulation mode particles. The instrument is used to measure how particles affect the Earth's radiation balance and visibility, i.e. scattering of visible radiation. [- 85.245.232.74 19:44, 2 January 2011‎ ]

after reading both articles (Nephelometer and Nephelometry), to my mind a distinction between gas and liquid could be made based upon apparatus design. However, the article already appears quite conflicted between the two for somewhat obvious reasons, so hence only a tentative suggestion. Writing an introduction and teasing apart the two may be a challenge. 79.68.129.48 (talk) 08:51, 25 August 2009 (UTC)Reply
