These data are used for the manuscript "Imprints of Ocean Chaotic Intrinsic Variability on Bottom Pressure and Implications for Data and Model Analyses" to be submitted to Geophysical Research Letter. Uploaded data include: [1] ext_int_quater_deg.nc: atmospherically driven and intrinsic variations for subseasonal, intra-annual and mean seasonal bottom pressure signals at model original resolution. [2] ext_int_3deg.nc: atmospherically driven and intrinsic variations for smoothed subseasonal and intra-annual bottom pressure signals at 3*3 degree resolution. [3] ext_int_10deg.nc: atmospherically driven and intrinsic variations for smoothed intra-annual bottom pressure signals at 10*10 degree resolution. [4] meanseason_timeseries.nc: Time series of mean seasonal bottom pressure signals from all 50 ensemble members over Agulhas Current region and Argentine Basin.
