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.

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.

here is my public persona and I stand for what I say. I think it is safe to say that this is a sentiment shared by many in my network and probably more around here.
A note for those in the industry and govt wanting to have more people entering STEM fields, reduce the load of what it takes to do science.
At this pace, one does not feel like encouraging younger generations to enter the field.
To keep in mind as this applies to any areas with 🔥activity . Just after fires in Patagonia days ago subsided, they became active dust sources. In AQ we focus on fires but the reality is that "remobilized ashes is dust activity. The difference from the view point of AQ is not relevant.

Starting the year with #highlatitudedust activity in northern Patagonia.
Unusual in this case is the fact that wind direction is from the E and SE, quite unusual for dust activity.

#highlatitudedust in #Alaska in time to say goodbye to the year.
This is a difficult image to interpret just using VIS channels, but there is dust (red arrow) and ocean foam plus blown snow mixed with blown sea bubble and marine aerosols (yellow).Dust is confirmed by low visibility in webcam.

As I noted in a posting few weeks back, this is a place I used to go often. A place for meetings and inspiration.
I will miss it.

Almost in the last day of the year and with sources spread through 2000kms, large plumes of aerosols (in this case #highlatitudedust and #smoke) from Patagonia are drifting into the SW Atlantic today.

Why is this important?
Because if drops are too small, they do not precipitate thus no rain. Thus it is important to understand how this operates.
Mt Michael 🌋 (S. Atlantic) shows an example of volcanic emissions making a cloud brighter by the same process that human air pollution change cloud reflective properties.
This why it is of interest to study aerosols-cloud interactions.

In fact, it degrades the quality of review and worsens the problem in that it gives less incentive to accept to do a review.

Well, I largely agree in the part related to creativity and breakthroughs.
But there are aspects of it that has made life better for modern scientists and are here to stay :

More #highlatitudedust activity today in Patagonia with two large clouds that combined span a pretty large area.
The large extension of the dust cloud makes it more likely for dust to reach Antarctica and remote Southern Ocean.
