    in both ends of the Americas yesterday! in the Yukon river valley (61N) and Colhué Huapi lake (46S) in . Nice example of activity highlighting common geophysical phenomena in two very different seasons in very different environments.

    There have been some nice images of Saunders Island recently, like this one from Jan 20. Hoping and have some ground truth.. Copyright 2020 Planet Labs Inc.

    As the sun sets over S. America, lots of aerosol activity is clear : in the north and in central Patagonia.

    Lower pollution levels seen from space in China because (probably) lower activity due to health concerns.

    It's been a week of more activity in , shows cloud on top of the with high concentration of haze (or vog), AODs are moderately high.

    wow, nice. I can image that in the next version it will be possible to see the little penguin colonies on that beach.

    High res image from of Saunders Is in , volcano plume is visible, contrast is poor but it can be improved by some magic wizards like , and couple of my twitter friends, direct link to image

    The size of this smoke cloud is significant and this estimate is using a metric only sensitive to really dense smoke , there is more up there below the detection limit. The specific impacts of such large phenomenon are not clear and will take some time to find out.

    This is fascinating and happening right now: a high altitude gigantic smoke cloud has been meandering for more than a week between the Pla and tip of S. America. Not clear the implications of it but a lot of interesting science may come out of it
