TL;DR: In this article, the authors investigate community level concentrations of fine particulate matter (PM25), nitrogen dioxide (NO2) and sulphur dioxide (SO2) associated with cruise ships in James Bay, Victoria, British Columbia (BC), Canada Data obtained over four years (2005-2008) at the nearest air quality network site located 35 km from the study area, a CALPUFF modeling exercise (2007), and continuous measurements taken in the James Bay community over a three-month period during the 2009 cruise ship season were examined.
TL;DR: In this article, a bottom-up methodology was developed to assess the amounts of atmospheric pollutants emitted by all ships in port and its impact on the atmospheric pollution, which can be used to estimate shipping emissions in other port and/or regions and hence may serve as an input for other researchers and policy makers working in this field.
TL;DR: The results of evaluations of transport and dispersion models with field data are summarized in this article, where the California Puff (CALPUFF), Hazard Prediction and Assessment Capability (HPAC), and Chemical/Biological Agent Vapor, Liquid, and Solid Tracking (VLSTRACK) models were compared using two recent mesoscale field datasets, Dipole Pride 26 (DP26) and the Overland Along-wind Dispersion (OLAD).
Abstract: Results of evaluations of transport and dispersion models with field data are summarized. The California Puff (CALPUFF), Hazard Prediction and Assessment Capability (HPAC), and Chemical/Biological Agent Vapor, Liquid, and Solid Tracking (VLSTRACK) models were compared using two recent mesoscale field datasets—the Dipole Pride 26 (DP26) and the Overland Along-wind Dispersion (OLAD). Both field experiments involved instantaneous releases of sulfur hexafluoride tracer gas in a mesoscale region with desert basins and mountains. DP26 involved point sources, and OLAD involved line sources. Networks of surface wind observations and special radiosonde and pilot balloon soundings were available, and tracer concentrations were observed along lines of whole-air samplers and some fast-response instruments at distances up to 20 km. The models were evaluated using the maximum 3-h dosage (concentration integrated over time) along a sampling line. It was found that the solutions were highly dependent upon the di...
TL;DR: In this paper, the authors evaluated the performance of two Gaussian dispersion models (CALPUFF and ISCST3) for predicting downwind odor concentrations and back-calculating area source odor emission rates.
TL;DR: In this paper, the authors presented selected results of an urban scale analysis of air quality in the Warsaw area, basing on the emission and meteorological dataset for the year 2012.
