Meteorological controls upon ground level concentrations of smoke and sulphur dioxide in two urban areas of the United Kingdom

摘要: Abstract Meteorological controls upon ground level concentrations of daily smoke and sulphur dioxide in an urban area, Greater Manchester, were investigated using readily available meteorological parameters pollution data from the National Survey Air Pollution. Of numerous wind speed, degree-day temperature mixing height shown to be most important. These three important controls, together with a persistence parameter, represented by previous day's concentration, which was demonstrated air data, combined produce multiple regression equations calculate average for Manchester. The amount variance explained averaged 79% ( R = 0.89 ) 76% 0.87 concentrations. relative importance each parameter determined coefficients winter periods studied second area (Nottingham) found similar value suggesting that success schemes is likely other areas United Kingdom.
