#highlatitudedust activity today in central Patagonia

This morning , a rare view clear sky view of the Drake Passage, one of the most feared passages by sailors.

(well, it is almost 100% clear but not all but for practical purposes and this place , it is clear)

Three days in a row of continuous #highlatitudedust emission from Central Patagonia into the SW Atlantic

With increasing aridity in the US southwest, more #dust activity occurs and thus the need to better understand how the #health impacts of dust itself causes and/o the pathogens they carry. So it is not a surprise that we start to see such studies, here in one of the dustiest places of the USA.

Yesterday in Patagonia:
All day #highlatitudedust activity from sunrise to sunset injecting dust into the South Atlantic.

In fact dust activity started before sunrise , clearly seen in the IR image .

GOES image of today over the east of USA display a map of Aerosol optical depth a proxy of haze concentration, values in the 0.15 - 0.4 range are considerate moderate to high pollution.

GOES East image of today over the East coast with a big cloud of haze noted with a circle.

Thick haze off the East Coast. I am not sure what it is but it seems like it is smoke from fires in the south and east and around Mississippi Valley.

But today's image is more informational.

AODs values are higher for the clean S Atlantic air (but these are low if compared w/NE Atlantic).

Very notable how far it reached. Dust could potentially influence marine biology. Also it would certainly deposit over the glaciers of S Georgia Is

yesterday's #highlatitudedust event Patagonia had a long reach,

with a typical setting of a polar low transiting over the Drake passage, it drag a significant amount of dust into the SW Atlantic.

Yesterday's values of Aerosol Optical Depth (a proxy for dust concentration) report a generally clean region (note background values are removed). AOD values over the dust cloud are missing (no space to explain why here) , so in this case the actual amount emitted is underestimated from space

Yesterday's CHL from PACE shows a fairly typical distribution. Note the high levels of CHL just offshore of S. Georgia Island and Argentine sea shelfbreak.

yesterday #highlatitudedust activity in the Southern Hemisphere.

The source is the dry lake Colhué Huapi in the central Patagonia desert.
