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

Figure 5

Standard deviation difference between EXP2 temperature (°C) forecasts and Nature Run (a, b) and own cycle (c, d) analyses for the Northern Hemisphere (a, c) and Southern Hemisphere (b, d) extratropics regions. Blue regions indicate deterioration while red regions are indicative of improvement with respect to the control.
