Chemical measurements made during an air pollution event in Atlanta, GA have been compared with results from several photochemical simulations. Measurements included Os, primary reactive organic gases (ROG), aldehydes, PAN, total reactive nitrogen (NO,,) and HzOz, with vertical profiles for primary ROG. Photochemical models using two different chemical(More)
A new method of measuring the far-field pattern of single-mode optical fibers is presented. The method involves measuring the total power passed by a linear aperture in the far field and can be used with a white-light source. The measured far fields can then be used to determine the wavelength variance of characteristics such as the rms spot size (near or(More)
