Abstract [sv]

That air pollutants of different kind has impact on our climate can hardly have

avoided anyone during the past years environment explosion in the media. But how

is it actually with the reverse, i. e. the climate's impact on air pollutants? The aim

with our degree thesis is to try to find out if different weather factors, statistically

seen, promotes atmospheric pollutants and particles in the air and vice versa.

We got access to data on air pollutants and weather factors that was registered

during year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.

In order to do a statistical investigation of these data, and to be able to analyze if it

occurs relations of various kind, we used the statistics program SPSS. In SPSS we

worked with correlation, regression and multiple linear regressions in order to get

our statistical relations between atmospheric pollutants and weather conditions.

Our results showed that ozone is the atmospheric pollutant that is most weather

sensitive and ozone has also proven to have the strongest connections to the weather

factors. Also nitrogen monoxide, nitrogen dioxide and carbon monoxide are

considerably influenced by the weather, however not in equally big extent as ozone.

Sulphur dioxide and PM10 is on the other hand influenced in a low extent and it is in

these cases difficult to say if the weather actually has any influence at all. Wind speed

was, apart from sulphur dioxide and PM10, the weather factor that were strongest

correlated to the remaining atmospheric pollutants. The relative humidity and the air

pressure were the two factors that overall gave the weakest connections to the

pollutants. As a conclusion, we can say that our results can be seen as an indication

to the public about how sensitive people should minimize their time outdoors in the

inner city on cold and calm days. It is when these weather conditions occur that the

highest concentrations of atmospheric pollutants, statistically seen, can be found.

However, this does not apply for ozone. For ozone, they should instead be aware on

sunny and windy days as it, statistically seen, is days where high concentrations of

ozone can be found in the air.
