Fig. 5: Arctic SIC in August and September for different assimilation experiments and their differences from observations (2004–2023 average).

Fig. 5

The spatial distribution of mean SIC from the SIC-only experiment in (a) August, (b) September, and from the SIC-SIT experiment in (c) August, (d) September. The mean SIC differences: SIC-only experiment minus observations in (e) August, (f) September, and SIC-SIT experiment minus observations in (g) August, (h) September. Only the differences that exceed the 95% confidence level using a two-tailed Student’s t-test are presented, with the MAE indicated in the bottom left corner.
