Still some ash and dust blowing around

Yesterday, 28 May 2012 a satellite image showed a dust storm originating north of Dyngjujökull, near Jökulsá á Fjöllum. Whether this event, or the sum of many before it, the northern part of Vatnjökull is visibly brownish in the area near this source of dust storms.

Today in Fljótshverfi, east of Kirkjubæjarklaustur (underneath western part of Vatnajökull), PM₁₀ went well over 50 micro-g/m³, up to, and over, 150 micro-g/m³.

The forecast is for sunny, dry, days, so we can expect more of this if winds pick up – and not by that much.

High concentration of Particulate Matter around midnight past few days in Reykjavik due to ash re-suspension and dust storms

There has been a lot of ash and dust blowing around the southern part of Iceland the past few days. Sunny and dry, and not much wind needed to re-suspend the ash for instance.

Mainly in the evening that we have had high PM10 concentration here in Reykjavik area. This can be clearly seen from measurements at Grensásvegur, Kópavogur and Hvaleyrarholt.

In the south, at Raufarfell, there was a lot of PM10 mid-day 21 May 2012.

Dust storms in cold dry weather and strong winds

Yesterday, today, and probably for the next couple of days, we expect dust storms off the sandur and ash fallout areas in the south of Iceland. There is no rain in forecasts in the south till Friday, and tomorrow the forecast is for a strong northerly wind still (13 m/s), then more SE at 7 m/s on Wednesday, which might be enough.

At 12 on Monday, 14 May 2012.

Satellite image from 12:20 today shows a dust storm just east of Mýrdalsjökull.

Yesterday, around 15:10 there was also a dust/ash storm visible.
