Analysis of local dust plumes using ground- and satellite-based remote
sensing supported by surface measurements
Abstract
The Kluane Lake region in the Canadian Yukon territory is subject to
regular drainage-flow dust plumes emanating from the Slims River basin.
We have recently employed ground- and satellite-based remote sensing
(RS) techniques to analyze the complementarity and redundancy of such RS
retrievals relative to springtime Kluane Lake measurements made using a
suite of microphysical and meteorological instruments. Our preliminary
results include a correlation analysis between ground- and
satellite-based CM (coarse or super-μm mode) AOD (aerosol optical depth)
retrievals and between ground-based CM AODs and their surface
microphysical analogues of particle-volume concentration, supported by
1.5 μm Doppler (HSRL) lidar profiles. The analysis includes an
opto-physical interpretation of strongly and weakly correlative
illustrations.
