Available dataset

The dataset showing here will also be available in the Arctic Data System archiving System (ADS) operated by the National Institute of Polar Research (NIPR). Currently, we are applying to register them with the ADS. New Dynamic Ocean Topography using the retrieval from satellite radar altimeters (0.2 x 0.2 degree grid) Using the measurements from the CryoSat-2/SIRAL (L2GDR from ESA), Sentinel-3A, Jaosn-2 and Jason-3 (Corrected Sea Surface Height from CMEMS), the sea surface height (SSH)in the Southern Ocean was combined. After SSH was obtained, we combined them and subtracted the geoid height (GOCO05c) from the SSH and finally we obtained Dynamic Ocean Topography (DOT). To build grided dataset, we interpolated DOT using the the Topographic Constraint Scheme proposed by Shimada et al. (2017, JAOT). Data period: Jan 2011 to Dec 2022 Spatial resolution:0.2 degree File format: MAT file (MATLAB) Dataset can be downloaded from here.
