Dust and ash storm
Still dry weather, and wind, and lot of dust and ash blowing around. Source of particulate matter in Reykjavik from south of Langjökull; not only ash. Also, a clear source on Vatnajökull (see animation below).
This made for poor air quality, as well as poor visibility. An example from greater Reykjavik area below. View from underneath Helgafell towards Esja.
Satellite images show this well (images from NASA/Rapidfire).

Ash blowing off Vatnjökull
Today, 10 September 2011, there is a lot of ash blowing off the surface of western Vatnajökull.
There is more ash blowing around, as can be seen from the satellite image from 12:30 today.

The source is also quite clearly seen on this image, taken at 12:15.

Dust and ash storms in Iceland today
Sediments from pro-glacial lakes near Langjökull, and ash from the Eyjafjalljökull and Grímsvötn eruptions (most likely mixture of those) were blowing around today !

Made for very bad air quality, for instance at Raufarfell.

Article about dust storms and air quality
An article about dust storms and air quality in Reykjavík was just published in the journal Atmospheric Environment.
Here is a link to the corrected proof http://www.sciencedirect.com/science/article/pii/S1352231011005061.
Also welcome to drop me an e-mail for the final version.
The reference is:
