Air quality guidelines and standards have an important role to play in the management of air quality. ...
The Apple Watch already integrates air quality data in some locations. This data is, however, still limited in its spatial and temporal accuracy. ...
Systematic collection of long term meso- to large-scale datasets of ambient air quality provides an indispensible means for air pollution monitoring. ...
In particular the results can be used for parameterisation of dynamic and diffusion processes in PBL under such conditions.Keywords: non–local stable regimes, non–local neutral regimes, free flow stability, generalised bulk Richardson parameterisation, turbulent fluxes, air quality, air pollution, atmospheric dispersion modelling, ...
Gaussian and Lagrangian model runs are evaluated in comparison to field data from the Odour Release and Odour Dispersion (OROD) project and to wind tunnel data from the Mock Urban Setting Test (MUST). Different statistical metrics are discussed. The results illustrate once again that a good model performance is strongly dependent on the model input (e.g., terrain data, roughness ...
Therefore, it is relevant to develop a good prediction methodology for the concentrations of these pollutants. Statistical models based on Multiple Regression (MR) analysis and classification and regression trees analysis were developed successfully. The models were applied in forecasting the average daily concentrations for particulate matter and average maximum hourly ozone ...
At the Workshop on Operational Short-Range Atmospheric Dispersion Models for Environmental Impact Assessment in Europe, Lee and Irwin (1994) presented a methodology for conducting an objective comparative evaluation of two or more air quality models. The methodology involved the use of bootstrap resampling to allow computation of confidence bounds on model ...
This work aims at developing and validating a numerical air quality operational forecasting system that will be applied over Portugal. ...
In the framework of the Integrated Decision Support System for air quality assessment and management operating at the Emilia-Romagna Region Meteorological Service, an appropriate meteorological input is necessary: 1) to provide meteorological information for evaluation of the pollution data observed at the urban monitoring stations; 2) as input data to run daily ...
