"Elemental concentrations of airborne particulate matter at the Boulder Atmospheric Observatory have been analyzed as a function of height, time, particle size, anthropogenic activity, surface conditions, and various meteorological parameters. Aerosols were sampled at heights up to 49 meters during a one week period when the ground was at least partially covered with snow and the bottom 100 meters of the atmosphere was very stable"--Abstract. / Typescript. / "April, 1982." / "Submitted to the Department of Meteorology in partial fulfillment of the requirements for the degree of Master of Science." / Advisor: William H. Mach, Professor Directing Thesis. / Includes bibliographical references (leaves 117-121).

<p>That air pollutants of different kind has impact on our climate can hardly have</p><p>avoided anyone during the past years environment explosion in the media. But how</p><p>is it actually with the reverse, i. e. the climate's impact on air pollutants? The aim</p><p>with our degree thesis is to try to find out if different weather factors, statistically</p><p>seen, promotes atmospheric pollutants and particles in the air and vice versa.</p><p>We got access to data on air pollutants and weather factors that was registered</p><p>during year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.</p><p>In order to do a statistical investigation of these data, and to be able to analyze if it</p><p>occurs relations of various kind, we used the statistics program SPSS. In SPSS we</p><p>worked with correlation, regression and multiple linear regressions in order to get</p><p>our statistical relations between atmospheric pollutants and weather conditions.</p><p>Our results showed that ozone is the atmospheric pollutant that is most weather</p><p>sensitive and ozone has also proven to have the strongest connections to the weather</p><p>factors. Also nitrogen monoxide, nitrogen dioxide and carbon monoxide are</p><p>considerably influenced by the weather, however not in equally big extent as ozone.</p><p>Sulphur dioxide and PM10 is on the other hand influenced in a low extent and it is in</p><p>these cases difficult to say if the weather actually has any influence at all. Wind speed</p><p>was, apart from sulphur dioxide and PM10, the weather factor that were strongest</p><p>correlated to the remaining atmospheric pollutants. The relative humidity and the air</p><p>pressure were the two factors that overall gave the weakest connections to the</p><p>pollutants. As a conclusion, we can say that our results can be seen as an indication</p><p>to the public about how sensitive people should minimize their time outdoors in the</p><p>inner city on cold and calm days. It is when these weather conditions occur that the</p><p>highest concentrations of atmospheric pollutants, statistically seen, can be found.</p><p>However, this does not apply for ozone. For ozone, they should instead be aware on</p><p>sunny and windy days as it, statistically seen, is days where high concentrations of</p><p>ozone can be found in the air.</p>

Effective management of air quality in Shanghai, China, requires an understanding of the emissions, chemistry, and local meteorology. The local and regional factors responsible for the spatial and temporal variations in NO2, SO2, and PM10 concentrations observed at 10 air quality monitoring sites in Shanghai from August 1, 2003 to July 31, 2004 were analyzed in intersite, interspecies, and species-meteorology correlations.
