#highlatitudedust activity this morning in the Valley of Ten Thousand Smokes (AK) visible from space (early overpass Terra) and the FAA webcam.

#highlatitudedust activity in southern Patagonia yesterday late into the evening.

Several dust sources along hundreds of km along with dust cloud and plumes that extend as long .

And this morning #highlatitudedust activity continued in Patagonia, so mostly likely there was dust emission all night.

More #highlatitudedust activity today in Central Patagonia.

By sunset over Patagonia today, copious amount of #highlatitudedust was being injected in the southern Atlantic region.

This morning #highlatitudedust in central Patagonia, copious amounts are reaching the city of Comodoro Rivadavia , where webcams show significant visibility decrease.

Another all day cloudy in Patagonia, where lake Coluhe Huapi (next to Sarmiento in image) was active all day. This time there is no satellite view to confirm but at least there are some surface webcams that can confirm. Note there is more #highlatitudedust in suspension than yesterday.

All day cloudy in Central Patagonia according to GOES. Very windy and in between clouds High res VIIRS and surface camera both confirms #highlatitudedust activity. This is activity will likely undereported since no satellite can make sucesible in these cloudy condition

Following up on the #highlatitudedust event in Patagonia, yesterday's dust cloud is now +1000km going well into the #SouthernOcean .

#highlatitudedust activity yesterday near Kodiak Is (Alaska), resuspended dust from the Valley of Ten Thousand Smokes.
Note the contrast between both images taken from different sensors about the same time.
In one image, the dust is very clear whereas the other is not so.
The reason .. 1/2

#DYK that #Iceland has 15 000km2 of sandy deserts (yes, a desert)?

Much of it old volcanic ash either old deposits or after being processed by glaciers.

As a result there is quite a bit of #highlatitudedust activity even in the cold months as the images from this November show.

Yesterday a low pressure center arrives to Patagonia (in yellow), and it triggers dust activity (red), cloud convective activity (green) and exacerbates a forest fires (orange).

#highlatitudedust cloud in Patagonia today blowing over the city of #ComodoroRivadavia and it is also visible from a surface webcam looking east. Despite the cloud is over the city, the camera view is not as spectacular , the difference is mostly due different conditions both sensors observe 1/

#highlatitudedust activity continues in Patagonia this afternoon.

Note the succession of images.
There was snow on the ground in the morning, then it melted and then dust activity.

Good example illustrating that you do not need hot weather to have a dust storm.

Yesterday, sunset over #Patagonia, with a thick #highlatitudedust cloud emitted from the northern shore of lake Colhué Huapi.

After yesterday's #highlatitudedust activity in Patagonia, this morning at sunrise a sizeable #dust cloud is in suspension off the coast of #Argentina

So why the interest in #highlatitudedust?
... because it impacts how clouds form and precipitate thus changing they way they reflect sunlight and emit heat (it can go either way depending many conditions) ,here is a new paper explaining its importance and impacts.

As sun sets over Patagonia, a cloud of #highlatitudedust peaks out of a cloud deck. The source (lake Colhué Huapi) was probably active most of the day but could not be confirmed because cloudiness.
Monitoring activity like this is important for a number of biogeochmical and paleo applications.

Just published: “Remote sensing [RS] detectability of airborne Arctic dust”.
As I am new to Bluesky, I would appreciate everyone who could share the paper with the #highlatitudedust community and help connect me with them. @sangasso.bsky.social

Remote-sensing detectability of airborne Arctic dust
Abstract. Remote-sensing (RS)-based estimates of Arctic dust are oftentimes overestimated due to a failure in separating out the dust contribution from that of spatially homogeneous clouds or low-alti...

Resuspended volcanic ash is a type of #highlatitudedust activity as this image over the Kampchatka Pla illustrates.

The N. Pacific #marinecosystem tends to lack many nutrients that ash contain, so it is of interest to better understand the impact of the deposited ash downwind.

An extra-polar low pressure system as shown here is the transport mechanism by which #highlatitudedust and smoke are distributed through the #SouthernOcean and eventually reach #Antarctica.

The haze noted is dust from yesterday's dust activity in Patagonia.

More #highlatitudedust activity in the southern coast of #Iceland in the last two days.

Contrast is poor because there isn't much sunlight to reflect. This is typical on how satellites observe high latitudes.

#highlatitudedust activity today in the Patagonia desert. Dust sources are distributed along ~ 900km , sending dust into the South Atlantic and Southern Ocean.

Another day of #highlatitudedust activity in central Patagonia, with a pretty sizeable dust cloud going into the SW Atlantic as the sun sets over the area.
