Figure 2.2: <strong>AIRS</strong> Vis/NIR channels 1 through 4 overlaid with the spectrally similar MODIS channels.<br />
Transmittance and spectral surface albedo are plotted on the same figure. Note that the <strong>AIRS</strong> response<br />
functions shown are based on estimates made before testing of the actual flight hardware. See Fig. 1.1 for the<br />
latest response functions.<br />
