Prediction of aircraft noise around airports is traditionally assuming horizontal soft ground. This report describes a new calculation program, NORTIM, that automatically takes into account the influence of topography on aircraft noise propagation. It is directly based on INM version 4.11 with respect to input data formats and basic algorithms. NORTIM is capable to calculate all the most commonly used L(eq) and L(Amax) based noise descriptors, including the influence of terrain height, terrain slope variation, terrain surface properties and shielding effects. The development of NORTIM is made in close connection to a NATO CCMS effort in this field, ensuring international cooperation on algorithms, data compatibility and comprehensive verification measurements.
