Effects of Ocean Ecosystem on Marine Aerosol-Cloud Interaction
Figure 4
Seven-year (2002–2008) averaged daily data for (a) MODIS AOD at 550 nm and the differences between MODIS AOD and parameterized ss-AOD at (b) 550 nm and (c)1020 nm. The ss-AOD is calculated using Smirnov et al. [57] regression. Red boxes on Figure 4(a) indicate seven regions where time series analyses are carried out. Position of each boxes (latitude and longitude) are given in Table 4. Letters A and B denote locations of previous study areas of Smirnov et al. [57] at Midway Islands (28.2°N and 177.4°W) and Mulchay et al. [58] at the Mace Head station (53.3°N, 9.9°W), respectively. The study region of Glantz et al. [59] encompassed large areas of the North Pacific Ocean, roughly from 180°W to 160°W and 15°N to 45°N.
