Dust and sand particles whipped up from the Sahara will once again blanket skies over Europe this weekend, impacting air quality, the European Union's Copernicus satellite monitoring service said Friday.

It said wind predictions showed a "substantial plume" of Saharan dust would hit southern Europe over the weekend into next week, reaching as far north as Norway.

Mark Parrington, senior scientist at the Copernicus Atmosphere Monitoring Service, said that like a similar event earlier in February, the dust would likely be visible to the naked eye in the skies across Europe.

"Dust plumes from the desert can cause red skies, limited visibility or stains on cars and windows from dust deposition, but these impacts are difficult to predict quantitatively as far as four or five days in advance," he said.

Parrington said it was likely that the "high concentrations" of dust would affect air quality and could have some health impacts.

A previous dust cloud in early February darkened the skies in many regions of western Europe, carrying particulate concentrations "several hundred times" more than normal, Copernicus said.

ACTIVATE begins second year of Marine Cloud Study
Hampton VA (SPX) Feb 10, 2021
A NASA airborne study has returned to the field for a second year of science flights to advance the accuracy of short- and long-term climate models. The Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) began the third of six planned flight campaigns - two campaigns each year beginning in 2020 and ending in 2022 - in late January at NASA's Langley Research Center in Hampton, Virginia. Cloud formation in the atmosphere depends on the presence of tiny particles c ... read more
