The regions along the Arab Gulf received some rain on 22–25 February 2006. During the following nights patches of low clouds and/or fog formed especially inland of the United Arab Emirates. The fog event of 27–28 February is remarkable for the extent of the cloud cover that encroached upon a couple of oil fires along the southern border.

The RGB composite on 28 February at 02:30 UTC (see left image) shows this moment during maximum southward extension of the cloud cover, just before sunrise. The animated image sequence combines the Fog RGB (night) with the Natural Colours RGB (day). Note that the time resolution increases from hourly intervals between 27 February at 19:00 UTC and 28 February at 01:00 UTC to 15-minute intervals, thereafter.

Note: The IR8.7 channel, which over Euope is often used for the detection of fog/low clouds, is not practical over arid areas due to the low emissivity of sand in this channel. On the other hand, at these low latitudes the sunrise is more rapid than over Europe so that visible imagery shows fog already in the first slot after sunrise.
