Dust plumes in the Canadian Arctic have important climatic change (CC) impacts on (i) snow and ice (darkening and thus premature melting) and (ii) as nuclei for cloud formation (cloud reflectivity is a poorly characterized but key CC parameter). Ground measurements of dust in that region are rare. We characterized plumes close to their drainage basin sources using ground- and satellite-based remote sensing (RS) estimates of such key parameters as plume height, speed, and opacity (concentration).
