Quite a lot of PM10 at Raufarfell on 16 July 2010, close to 300 micro-g/m3 the 24-h average, while at Vík it was close to 70 micro-g/m3, but at Hvolsvöllur it was good, just around 10 micro-g/m3.

Soon after midnight on 17 July there is a large, and sudden, increase in PM10 at Vik, so we expect higher average for 17 July than the day before.

This increase is probably due to increased wind speed in the surrounding area, or higher in the atmosphere (top of Eyjafjallajökull), since no increase was measured in wind speed at Vik.
