Maritime-Continental Contrasts in the Properties of Low-Level Clouds: A Case Study of the Summer of the 2003 Yamase, Japan, Cloud Event

Figure 15

Scatter plots of optical thickness ( ) and effective radius ( ) of lower-level cloud over land (a) and ocean (b) in the analysis area at 0410 UTC July 19, 2003. The blue (red) line represents a normalized histogram of ( ). The values in the panels represent the numbers of observations, the maximum values in the histograms, and the averages and standard deviations of (blue) and (red). The solid lines show the cloud droplet number concentration (from top to bottom): 10, 30, 50, 100, 300, and 800 [ ], and the dashed lines show the liquid water path (from bottom to top): 10, 50, 100, 300, and 800 [g m−2] calculated using (12) and (13) of [23], respectively.
