Oman: biggest dust storm in over a decade

Oman: biggest dust storm in over a decade

MODIS-Terra. 7 Mar 2015

A spectacular dust storm hit portions of Oman last Saturday 7 and Sunday 8 (click image on the right to enlarge it). High winds coming off the deserts of southern Iran are what caused the event.

Dusty conditions prevailed over many governorates of Oman on Saturday leading to reduced visibility and even delaying of flights at Muscat International airport for a few hours.

The Director General of Meteorology and Air Navigation (DGMAN), on Saturday, tweeted that the "horizontal visibility at the Muscat International Airport ranged from 200 to 500 metres due to the dusty weather."

Dr. Amin Nawahda, from the Sohar University, informs that PM2.5 levels at the campus exceeded 350 μg/m3 (see figure on the bottom). The air quality guidelines of the World Health Organization (WHO) are a mean of 25 μg/m3 for a 24-hour period and a mean of 10 μg/m3 annually. People most at risk from PM2.5 pollution exposure include those with heart or lung disease (including asthma and chronic obstructive pulmonary disease-COPD), older adults, and children.
