Summary
Presentations will focus on scientific developments in the field of Earth observation for aerosols, clouds, and dust plumes in the Arctic.
Detailed description
Presentations:
- Recent results on the ground- and satellite-based remote sensing of Arctic aerosols & clouds over high- and low-Arctic sites
- Local dust plume analyses using ground- and satellite-based remote sensing over high- and sub-Arctic sites
Recent results on the ground- and satellite-based remote sensing of Arctic aerosols & clouds over high- and low-Arctic sites
Presentation 1 (in English)
From 11:00 to 11:30 a.m.

Recent results obtained as part of the Signatures of aerosol-cloud Interaction over the Arctic project, phases 1 and 2 (SACIA and SACIA-2), will be presented. These include satellite- and ground-based remote sensing measurements of locally and distantly emitted dust, smoke from biomass burning events, sea salt during the polar winter, and volcanic sulphates generated by strong volcanic events. Synergistic results employing comparisons with aerosol and cloud simulations will also be presented.

Presentation 2 (in English)
From 11:30 a.m. to noon

Remote sensing analyses of local dust emissions at the Kluane Lake (sub-Arctic) and Eureka (high-Arctic) sites will be presented. The Lhù'ààn Mân' (Kluane Lake) region in Yukon is subject to regular drainage-basin, wind-induced dust plumes emanating from the Slims River basin. We employed ground-based passive and active remote sensing techniques to analyze the complementarity and redundancy of remote sensing retrievals relative to microphysical measurements. This dust emissions site is just one of many current and potential future proglacial dust sources in the Canadian North. More recent passive and active ground- and satellite-based local dust plume measurements acquired at the high-Arctic PEARL complex in Eureka, Nunavut, will also be presented. All results will be contextualized by an analysis of the complementarity of the long-range transport of dust from springtime Asian dust storms.
Note: Both presentations will be given in English, but attendees can ask questions in the official language of their choice.
