Contents:

Daily ocean bottom pressure anomalies over 2007-2009 obtained from two global forward simulations:

DEBOT (David Einspigel Barotropic Ocean Tide Model): 1/3° horizontal grid spacing, single-layer model

MITgcm LLC270 (Massachusetts Institute of Technology general circulation model, Lat-Lon-Cap 270): nominal 1/3° horizontal grid spacing, 50 vertical layers

Common specifications:

Yearly files (yyyy) for each model run (DEBOT_OBP_n180_yyyy.nc, LLC270_OBP_n180_yyyy.nc)

Temporal mean 2007-2009 reduced

Daily fields centered at 12 UTC

Units: cm of equivalent water height

Data given on regular 1° grid

Synthesized from spherical harmonic expansion truncated at degree 180 (n180)

Degree 1 terms: included

Static atmospheric contribution to bottom pressure: included

Atmospheric forcing: ERA-Interim (6-hourly)
