TUPOS: A Multiple Source Gaussian Dispersion Algorithm Using On-Site Turbulence Data

TUPOS is a refinement of the MPTER air quality model that can exploit information about the vertical wind profile and has improved methods to compute the plume fluctuations and effective height as well as its partial penetration in the stable layer. It works for short time intervals with multiple point sources, but assumes flat terrain conditions and cannot account for deposition or fumigation episodes.

KEYWORDS

area: air quality
objectives: simulation
description: gaussian plume, vertical wind data, point sources, short range, short term, inactive pollutant
