We have ploted the AIRS channel number vs channel center frequency data. Note that the channels in the 970-1050 cm-1 (Array 11 = Module6) and 1330-1450 cm-1 (Array7 = Module3) regions are in a different direction than the other channels.
plot of channel number vs frequencyWe have ploted the fixed gases amount multiplier for the 48 regression profiles (at 5 angles each) vs. the 100 AIRS layers. Two approximations to calculate FIXMUL are compared. Note that since FIXMUL is always close to unity, the relative errors in FIXMUL are larger than the small numbers might suggest.
