Some New Practical Models for Visibility for German Locations Where No Records Exist.

Abstract

Given only month, time of day, and the elevation and surrounding elevations for an arbitrary location in Germany, models are developed for estimating probabilities of visibilities less than a specified distance. The two-parameter Weibull model is used. For a given month and hour period, the parameters are functions of elevation and average elevation of the surrounding region. The models are developed using a somewhat sophisticated nonlinear, least squares regression program. Evaluation is accomplished using 'sample-reuse,' a relatively new technique in which a valid independent evaluation of the model is made using the same observations used to develop the model.
