| Zusammenfassung |
| Aircraft-based measurements of aerosol light-scattering coefficient, cloud
condensation nuclei (CCN) measured directly or by proxy, and aerosol
chemical composition are reported for three different years in the region of
the large stratocumulus deck off the California coast. Receptor modeling is
used to differentiate the contributions of the main aerosol sources to the
light scattering and CCN activity. The contribution of anthropogenic sources
to the two climatically important aerosol parameters (for direct and
indirect forcing) varied from year to year but, on average, was found to be
67% in the case of CCN concentration and 57% in the case of
light-scattering coefficient. |
