This research focuses on aircraft noise exposed urban spaces around Amsterdam Schiphol airport. In particular, a case site in Rijsenhout is studied, where a representation of the noise wave propagation due to refraction is performed. Subsequently, a series of landscape configurations regarding geometry are gradually tested through acoustic...

We develop and study two approaches for the prediction of optical refraction effects in the lower atmosphere. Refraction can cause apparent displacement or distortion of targets when viewed by imaging systems or produce steering when propagating laser beams. Low-cost, time-lapse camera systems were deployed at two locations in New Mexico to...

This work details the analysis of time-lapse images with a point-tracking image processing approach along with the use of an extensive numerical weather model to investigate image displacement due to refraction. The model is applied to create refractive profile estimates along the optical path for the days of interest. Ray trace analysis...
