Accuracy assessment of ocean tide models around Antarctica
Accurate ocean tide models for the circum-Antarctic seas are required to remove unwanted signals from floating ice elevation and space-borne, time-variable gravity measurements ( e. g., GRACE). We present accuracy assessments for several global ( CSR4, FES2004, FES99, GOT00.2, NAO. 99b, TPXO6.2) and...
