700 Years of Indian Ocean Basin and Dipole Modes Reconstructed through Data Assimilation

The file contains the reconstruction dataset used in the article "700 Years of Indian Ocean Basin and Dipole Modes Reconstructed through Data Assimilation". It includes a 2000-member ensemble of reconstructions along with the ensemble median. The dataset comprises reconstructed results for both the Dipole Mode Index (DMI), representing the IOD, and the Indian Ocean Basin-Wide (IOBW) index. Liang, R., Hu, J., Luo, J., & Zhou, Z.
