Impact of Argo Observation on the Regional Ocean Reanalysis of China Coastal Waters and Adjacent Seas: A Twin-Experiment Study

Figure 2

(a), (b), and (c) show the horizontal distribution of vertical averaged temperature RMSEs of three twin-experiments, respectively, using (2); (d) shows the difference of temperature RMSEs between Experiments 2 and 1, that is, Experiment 1 minus Experiment 2, and (e) is for Experiment 1 minus Experiment 3; (f) is for Experiment 2 minus Experiment 3. Unit: °C. Experiment 1 is a free run where no data is assimilated, while Experiment 2 only assimilates “conventional observations” and Experiment 3 assimilates all the “observations” including “conventional observations” and “Argo observations.”
