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.

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.

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.

The #dust outbreak has expanded dramatically—one massive plume spreading over the #ArabianSea, while another moves through the Strait of Hormuz into the #PersianGulf, reducing #AirQuality 😷 across coastal #Iran, the #UAE, and #Qatar. A broad, sustained regional event.

Nevada just let property insurers exclude wildfire coverage. Homeowners won’t realize until it’s too late that fire isn't covered. Expect shock, underinsurance, and scrambling for expensive new policies. Plus: pressure for a federal wildfire safety net. open.substack.com/pub/susanpcr...
What happens if property insurers are allowed to exclude wildfires from coverage?
“Are we just going to turn everybody loose and let the fires burn our houses down?” Nevada just did — and others may follow.
