Abstract. Bottom pressure estimates from three different GRACE gravity series (an experimental CSR swath series, ITSG2016, and ITSG2018) and two global ocean models (OMCT and MPIOM) are compared to Jason altimetry sea level anomaly estimates, in order to determine the accuracy of the GRACE and model data at sub-monthly time scales. We find that the GRACE series are capable of explaining 25–75 % of the sub-monthly altimetric variability over most of those ocean regions which have high signal strength. All three GRACE series explain more of the sub-monthly variability than the de-aliasing products they were created with do. Upon examination over finer frequency bands, the GRACE series prove superior at explaining that altimetric signal for signals with periods as short as 10 days.

Short summary
Bottom pressure estimates from three GRACE gravity series and two global ocean models are compared to Jason altimetry sea level anomaly estimates, to determine the accuracy of the GRACE and model data at sub-monthly time scales. The GRACE series can explain 25–75 % of the sub-monthly altimetric variability in most ocean regions with high signal strength. The GRACE series explain more of the sub-monthly variability than their de-aliasing model products can, to periods as short as 10 days.
