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.
