Climate effect of dust aerosol in southern Chinese Loess Plateau
over the last 140,000 years.
Geophys. Res. Lett., 36, L02707, doi:10.1029/2008GL036156.
The Earth's climate is influenced by the manner in
which solar radiation is absorbed and reflected in the
atmosphere. In the study, the approach evaluating the
radiative forcing of aerosol was used to analyze the climatic
effect of dust over the last 140,000 years in the southern
Chinese loess plateau. (1) Radiative effect of dust aerosol
was to reduce the solar radiation arriving at the surface and
thus to lead earth cooling. However, the grain size-driven
climatic feedback of dust aerosol was negative on shortterm
scale, i.e., to weaken the amplitude of climate
fluctuation. (2) Glacial-interglacial fluctuation was marked
in most optical properties of dust over the last 140,000 years.
High-frequent millennial scale fluctuations corresponding to
Younger Dryas, Heinrich events and D-O cycles dominated
most optical properties of dust aerosol. (3) The climatic
feedback of dust aerosol may be a contributor for the
climatic transition between glacial and interglacial periods.
STUDY NOTES: Optical properties data and calculated radiative and temperature
effects of loess aerosols over the past 140,000 years.
Data collected at Yangge, Weinan, Shanxi in the southern
Chinese Loess Plateau. The 12.0m section was sampled at
intervals of 2cm for the upper 2.0m, and 5cm for the lower 10m.
