| Zusammenfassung |
| Aircraft–based measurements of cloud condensation nuclei (CCN),
accumulation mode and Aitken mode number concentrations, cloud drop number
concentration (CDNC), and selected ancillary measurements are presented for
the three large, semi-permanent marine stratocumulus decks of the earth (in
the Pacific offshore of California and Chile and in the Atlantic offshore of
Namibia). Based on these data, a simple linear relationship between CDNC and
the accumulation mode number concentration (AMNC) is derived via regression.
The slope of the regression is 0.72 ± 0.04 with an R2 of 0.90,
higher than those found for CDNC-CCN linear regressions. Explanations of the
relatively favorable CDNC-AMNC relationship and its utility for climate
studies are discussed. |
