“…In this context, CAL-PUFF has been mostly applied for air quality management and risk assessments for cities and countries like Istanbul (Elbir et al, 2010), Beijing (Hao et al, 2007), and Thailand (Sakulniyomporn et al, 2011). In contrast, CALPUFF has also been used in short range but long-term dispersion studies in cases where complex flows induced by radical terrain and land use variability are deemed significant, with primary emphasis on model performance and validation (Cui et al, 2011;Dresser and Huizer, 2011) and exposure assessments (Macintosh et al, 2010). Furthermore, while perhaps premature and problematic, a growing body of knowledge is emerging on the viability of integrating Numerical Weather Predictions (NWP) with dispersion models for air quality assessments (USEPA, 2009).…”

“…It can calculate impacts of meteorological conditions that vary over time as a result of area effect on transport, removal, and chemical conversions of the pollutants [25][26]. Furthermore, the program also includes algorithms based on the distribution coefficient approach and dry-wet accumulation model [27]. CALPUFF splits the pollutants into a large number of different cells (puff) and each cell is influenced regardless of terrain conditions, meteorological conditions, chemical conversions, accumulations, and, in particular, time intervals [28].…”

Air quality modellings are highly useful systems used to investigate the possible impact of emissions diffusing into the atmosphere in any area they might have on that area. There are many modelling methods whose capacities are limited by their advantages and disadvantages or the equipment they use. In this study, therefore, both steady-state models (AERMOD and ISCST-3) and the Lagrangian model (CALPUFF) are used. This study has two purposes: one is to specify performance of the models. Performances were determined with various statistical methods such as fractional bias (FB), mean squared error (MSE), and geometric mean bias (MG). The other purpose of this study is to evaluate temporal and spatial variations of point (P), area (A), and line (L) -sourced CO and NO x emissions in the research area by using the modelling methods. The district of Körfez, which is one of the districts of the province of Kocaeli, was chosen as the study area.When the results obtained with modelling all P and A sources by three programs are analyzed, the highest annual concentration AERMOD, ISCST-3, and CALPUFF were found as 128.82, 86.96, and 201.30 µg/m 3 for CO, and 7.56, 26.31, and 6.10 µg/m 3 for NO x , respectively. On the other hand, when the results obtained with modelling all P and A and L sources by two programs are investigated, the highest annual concentration AERMOD and ISCST-3 were found to be 155.12, 92.46 µg/m 3 for CO, and 166.93 and 89.98 µg/m 3 for NO x , respectively. When contributions of the pollutant sources on pollution are evaluated, it was observed that area sources and line sources are more predominant than other sources for CO and NO x emissions. It was observed by analyzing the diffusion maps that residential areas in the district are more concentrated. Therefore, in the study the predicted and observed values were also compared with national and international limit values and determined to meet these limit values. According to the results obtained by evaluation of performances of the models with FB, MS, and MG statistical methods, performance sorting for NO x emissions was found to be ISCST-3 > CALPUFF > AERMOD, while for CO emissions it is given as

This analysis seeks to evaluate the impacts of an open-pit coal mine located in the north of Colombia. It was used as the main tool CALPUFF, model Lagrangian, to determine the dispersion and transport of PM 10 due to the emissions of the mining activities. The model was calibrated and validated with the environmental concentrations data of PM 10 in 5 receivers. It was determined the contributions above of 45 km distances from sources. We use the concept of intake fraction, which is defined as the fraction of material or its precursor released from a source that finally is inhaled or ingested by a population. The results of the model show that the PM 10 can be transported over long distances. to 50 km from the industrial zone of the mine, the average contribution of emissions of the mine can reach 9.12 µg/m 3 and to 60 km contributions of 6.13 µg/m 3 . The modelling estimates that simulations of domain extending about 45 km from the source would only capture on average 54.83% of the total population intake fractions of PM 10 , and less for many geographic settings. The results show that the emission of PM 10 is a problem of pollution on a regional scale. This analysis can serve as input to the competent authorities for better environmental management.
