Hello all, there are a lot of new people here so I thought of re-introducing myself. I am a Earth Observation (EO) aerosol scientist contracted to work for the only agency that has put people on the moon.
1/8
Below is an old self-introduction and description of what I have fun with (professionally speaking) .
The times are quite different than when I posted this, but well, we are still here, chugging along and hoping for the best.

Station Papa, about 1200km downwind from the Copper River dust plume, has a number of instruments to monitor biological activity year round, so it would a be a nice exercise to explore monitor its data in the context of these dust events.

BTW some have done this excerciae before, if recall correctly, Bishop et all (late 80s/early 90s), Boyd et Al (early 90s GBC) and I think Crusius et al (2020s, JGR ). there maybe more..
Passive degassing in Mt Curry 🌋in #Zavodovski Is. (South Atlantic).
Cloud nucleii in the plume enhance brightness in the overlaying clouds creating a #volcanotrack.

Latest images from N20 and N21 confirm more #highlatitudedust activity all along the coastline to west (Kodiak), center (Copper River Delta) and south east (south of Yakutat)
Meanwhile in Patagonia, activity continues with the #highlatitudedust cloud extending over the phytoplankton blooms (arrow) in the SW Atlantic.
Thick cloud in the distance obstructs clouds.

#highlatitudedust activity today in Patagonia, GOES image shows some dust in between clouds. But it is clear as seen from webcams on the ground in Comodoro Rivadavia.
One year, I counted the time it took me to write 4 proposals (3 as PI). If I recall correctly, it was 150-180 hours, about ~2.5 months which I got naught money out that effort (massacre year). And these were proposal that would fund me just ~0.25 FTE 1/n
At both end of the Americas , in Kodiak (Alaska) and Comodoro Rivadavia (Patagonia, Argentina) cloudy conditions prevail and no direct view from satellite to the surface. Both webcams in both sites confirm #highlatitudedust in suspension (images with poor contrast but believe me it is dust)

My old collection of >100 high resolution images taken by Pleiades satellites between 2013 and 2021.
My processing skills weren't very good and Bsky can't show full res, but here they are.
I'm planning to add more from time to time.
1. Beijing-Daxing Airport terminal in China ( 2021-10-26 ).
On the #solstice , more #highlatitudedust activity around the E and SE side of the Gulf of #Alaska with glacier silt blown off several glaciers termini and the Copper River Delta.
Three nice views from SNPP, N20 and N21

It is that time of the year again....., longest night in the northern hemisphere, longest day in the southern hemisphere
N20 image
more than a week long of almost continuous injection of #highlatitudedust well into the GoA.
Something to keep in mind when doing nutrient budgets in the
area.

But I think since there is more evidence around , it would be a good idea to do an update.

And the just arrived image from NOAA20 just arrived and confirms continued (already a few days like this) #highlatitudedust activity particularly from the Copper River Delta.
