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.

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.

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