Low-level mixing height detection in coastal locations with a scanning Doppler lidar

... heights below the lowest vertical gate, 42 % of the time at Limassol and 62 % of the time at Loviisa. The VAD-based mixing height estimates show that, at Limassol, in 58 % of the cases when mixing level height must be below the vertically-pointing altitude limit, there is a shallow mixed layer at the surface (Fig. 9). At Loviisa the VADs indicate a shallow ... mixing. Finally we have demonstrated that very shallow mixing layers can be present during the majority of the time that vertically-pointing measurements indicate no mixing; i.e. mixing height is below the lowest measurement at vertical. At Limassol, representing Mediterranean summer time conditions, such low mixing heights occurred only during the night: ... at the top of the lowest gate.

Recent advances in ion chromatography instrumentation and system optimization (e.g. greater column sensitivities, low flow rates, multiple eluents, and gradient elution) enabled this study to identify and quantify numerous LMW-DOC compounds at low (< 70 nM C) concentrations, which demonstrates a novel methodological approach to glacial LMW-DOC analysis.
