Abstract
This study reports satellite evidence for the most northerly blown dust activity yet observed on Earth. A systematic inspection of high-resolution satellite imagery identified active dust events and their sources >82°N in Peary Land, Greenland. In the absence of any local weather measurements, for all observed dust activity a focus period in April 2020 with multiple dust plumes, reanalysis climate data found the majority of dust events to be associated with wind speeds exceeding a typical threshold value for blowing sand and dust uplift. Wind direction variability points to dust-raising by cold airflow down-valley winds, likely from nearby ice masses.
