Very high levels of PM10 (and 2.5) at Heimaland, Hvolsvöllur high, Vik better on 2010-07-01

Very high levels of PM10 at Heimaland (631 micro-g/m3), high at Hvolsvöllur (224 micro-g/m3), but quite good at Vík (58 micro-g/m3) the 24-hour averages. Health limit as before 50 micro-g/m3.

Measured PM over the day on 1 July 2010. Quite windy from about 6 in the morning, and not wet enough at Heimaland.

For Heimaland I show both the PM10 values (red solid line), and the PM2.5 values (red dashed line). It is confusing that PM2.5 values are higher than PM10, since PM2.5 are included in the PM10 category. So, either some error in PM2.5 measurements, or PM10 is underestimated (quite badly).
