H/T to Santiago Gassó for bringing this event to our attention.

#sentinel2 had a not-so-centered overpass, but some of the northern plumes seem to me like sand although there are plumes coming of the pan further inland. #highlatitudedust @sheffield_dust @jobullard https://t.co/pBaIQf2Z3v pic.twitter.com/4hwnR59CNa
