Figure 21: Same as Figure 2, but for AMSU-a channel 5, which peaks at ~ 500 hPa.Figure 22: Same as in Figure 2, but for AIRS channel 215 (channel 92 in the 281 subset)which peaks ~ 450 hPa.Figure 23: Comparisons of the SSU brightness temperature at channel 1 (left), 2 (middle),and 3 (right) between calculations and measurements for November 2004.Figure 24: On the left is the static, zonal invariant, 500 hPa stream function (1e 6 )background error valid 2007110600. On the right is the flow dependentadjusted background standard deviation.Figure 25: The cloud liquid water bias term for AMSUA-NOAA15 channel 3 varies withtime during 2007042218 to 2007052218. The red curve initialized from zeroand the blue curve is the operational values used as a reference here.Figure 26: The global total bias for HIRS3-NOAA17 channels 2-14 and AMSUA-NOAA15 channel 3, 5, 7, 9 varies with time during 2006110118 to2007013018. The blue curve is the experiment values and the red curve is theoperational values used as a reference.Figure 27: TOVS period, 1979-1998, 4xdaily averaged, globally averaged, total biascorrection for MSU channels 1-4 (left) and SSU channels 1-3 (right).Figure 28: The yearly total of tropical storm reports stacked by the 8 geographical basinsfrom top to bottom, Western Pacific (W Pac), Southern Indian (S Ind),Southern Pacific (S Pac) , North Atlantic-Caribbean (Atl), Eastern Pacific (EPac), Central Pacific (Cen Pac) , Bay of Bengal and Arabian Sea.Figure 29: Time series of the percentage of detected tropical storms plotted globally andfor selected Northern Hemisphere basins: the Atlantic-Caribbean (ATL),Western Pacific (W Pac) and Eastern Pacific (E Pac) Oceans.Figure 30: The vertical structure of model levels as a meridional cross section at 90E. Theleft panels are for R1 (28 sigma layers) and right panels for CFSR (64 sigmapressurehybrid layers). The top panels are plotted as a linear function ofpressure to emphasize resolution in the troposphere and bottom panels areplotted in log(pressure) to emphasize stratosphere.Figure 31: Same as in Figure 30, but as a zonal cross section across Rockies at 40N.Figure 32: The global number of temperature observations assimilated per month by the- 85 -
