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

Figure 8

Standard deviation time series against the NR of EXP2 (red) and CNTL (blue) 850 hPa temperature (K) for 24 h, 72 h, and 120 h forecasts for the tropics (a) and extratropics south (b) regions. Indicated on the right is the percentage of cases where EXP2 improves over CNTL as well as the global std. difference.
