Record‐Breaking Easterly Dust Transport From North Africa to the Arctic: An Observational Study

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mineral dust drives Arctic climate variability, but accurate source attribution remains difficult due to plume mixing from the different regions. Using observations and HYSPLIT modeling, we characterize a record‐breaking trans‐continental dust intrusion (March 13–19, 2013) traversing from North Africa to the Arctic. Distinct from single‐source
