Research on atmospheric aerosols w/satellites, models & impacts such as atmos-ocean exchange processes (SOLAS!). Atmos. polarization radiative transfer, #physics overall. Sharing and commenting on papers and sat images of (my) interest #highlatitudedust
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.

A report published in @ametsoc.org on air pollution in Houston .
It does remind us that when Saharan #dust reaches the area after traveling 10000km, it makes a sizeable contribution , big enough that show be included in #airquality local forecasts.

#highlatitudedust activity this morning in the Valley of Ten Thousand Smokes (AK) visible from space (early overpass Terra) and the FAA webcam.
While Terra satellite is drifting (into an orbit from where it will be decommissioned), it is still capturing images.
Here a #volcanotrack Mt Michael in the S. Atlantic (9:30UTC) but in the overpass of SNPP (15:56) there is no trace of activity. This illustrate how ephemeral volcanic activity is.
In the #LithiumTriangle area today in NW Argentina, dust activity in the Dead Man dry lake (which says everything about conditions in this place).
Because emission is as such elevated place, dust is injected in the mid-troposphere were winds can carry it long distances including to Antarctica.
Lab study on morphology and water content of #seasaltparticles (SSA) at different wind speeds.
this is interesting for anyone doing optical detection of SSAs (like sizing) because changing in water content influence how size is inferred using optical methods.

Doing some ride-hailing on the side?
a recent @pnas.org article reports a study on how you can be to more efficient and make more money.

No need to wonder: @coveringclimatenow.org is hosting a free webinar panel. Join us THIS AFTERNOON:
And this morning #highlatitudedust activity continued in Patagonia, so mostly likely there was dust emission all night.

#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 .

This has been tried for decades and if it worked, we would know by now.
