Views of Sahara Dust over the Canary Islands (Spain) and Paris, France

April 15, 2021

Con Calima - Sin Calima - Satelite Dust3
Photographers: Jose Fernandez Arozena; Bertrand Kulik
Summary Authors: Jose Fernandez Arozena; Jim Foster
Shown above (top photo) are two views from the window of my home in
Santa Cruz de La Palma (Canary Islands), Spain, showing the
contrast between a normal view (right) and a view obscured by dust
carried westward by a storm originating over the Sahara Desert
(left). PM10 values greater than 700 ug/m^3 were recorded,
which is well above the range considered to be very poor air
quality (more than 300 ug/m^3). A satellite view of this storm is inset
at lower left.

The view at right was taken a week later when the Northeast Trade
Winds were blowing over the island of La Palma and sweeping the dust
and haze out to sea. Top photo taken on February 16, 2021; bottom photo
shows this dust layer as captured by Bertrand Kulik, above Paris,
France, on February 21, 2021.
