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

Figure 6

Profile of standard deviation differences (solid lines) for EXP2 (red) and CNTL (blue) against the NR for the tropics (a) and extratropics south (b) regions at 120 hr; broken lines represent the bias. The level of significance above 90% is indicated. The three variables UU (zonal wind, m/s), GZ (geopotential, dam), and TT (temperature, °C) are identified on the axis. Red markers on each side denote superiority of EXP2 and the blue markers denote superiority of CNTL.
