OBJECTIVE ANALYSIS OF SURFACE VISIBILITY,
Abstract
Three methods of computing a weighted average of surface visibility at gridpoints were developed and tested. These methods employ (a) a simple weighted average, (b) a weighted average using a transformation of the observed visibility to emphasize low values, and (c) a transformed variable that considers the area represented by a reporting station. Various options, such as grid spacing, size of the search area, weighting functions, and solution for indeterminate points, were tested with a total of 152 hr or airways data. Results indicate that the method used and selection of options are best defined by the user's requirements. (Author)
