Abstract
As part of most visibility monitoring programs, photographic images of landscape features are collected to help visualize the effects of variations in the spatial distribution of haze. These photographs are an effective way of communicating visibility impairment of landscape features to decision makers and the general public and are useful in providing stimuli for visibility perception and valuation studies. However, in most cases the spatial aerosol distribution is unknown, and the photo may not be an accurate depiction of assumed haze levels associated with aerosol and optical measurements at the location. An alternative approach is to use image processing techniques to display the visual impact of a modeled spatial aerosol distribution with well-defined optical characteristics. This chapter outlines an optical and image display modeling system that is used to depict visibility-impaired vistas or landscape features. The radiative transfer problem is discussed as it relates to modeling radiation fields associated with spatially nonuniform aerosol distributions, as well as modeling the effects of earth curvature on a radiation field under near-Rayleigh conditions. Example photos are presented that show how aerosols with different physio-optical characteristics and spatial distributions, varying relative humidity, and cloud cover affect the seeing of landscape features.
