Figure 4 compares the BKS SIE in the two datasets with the reconstructed BKS SIE.As seen above,it is unsurprising that the evolution of the SIE prior to 1979(i.e.,1958–78)in the two sea-ice datasets is different.The BKS SIE in the NSIDC dataset is more strongly correlated with the proxy(-0.64)and the reconstructed SIE(0.64)than the Hadley dataset is(-0.26 and 0.26;Tables 2 and 4).This finding suggests that the quality of the sea-ice data from NSIDC is better than that of the data from Hadley.The lower correlation(0.64)of BKS SIE in the Hadley dataset than that in the NSIDC dataset(0.76)with the reconstructed SIE during the whole period from 1958 to 2013 is in agreement with this assessment.Thus,the interannual BKS sea-ice data in the NSIDC data are relatively more reliable.
