Operation Manual for the Multi-Wavelength Abridged Polar Nephelometer

Abstract

The purpose of a polar nephelometer is to measure the angular scattering coefficients of atmospheric aerosols for light of a given wavelength over the angular range 0 to 180 degrees, either continuously or at a large number of fixed angles. The Abridged Polar Nephelometer describes in this manual measures only scattering at the angles of: 30 deg., 100 deg., 140 deg., but for five optical wavelengths: 0.325, 0.66, .095, 2.25 and 10.6 microns. The apparatus is packaged in four separate measurement modules which are, in turn, mounted in three portable environmental housings. This portable field instrument can be located in the outdoors environment. It operates automatically from a computer based operation and recording system located in a shelter which can be at a distance of up to 100 feet away. Keywords: Atmospheric scattering coefficients; Scattering phase functions; Instruction manuals.
