Impact Evaluation of Assimilating Surface Sensitive Infrared Radiance Observations over Land and Sea Ice from Observing System Simulation Experiments

Figure 7

Differences in anomaly correlation (%) at 850 hPa (a) and 500 hPa (b) for temperature between EXP2 and CNTL, validated against the NR, as a function of forecast lead time for the four regions indicated. Gray shading above the dotted line indicates that the impact is positive at 95% significance level.
