Description

Data supplement to: Schindelegger, M., Harker, A. A., Ponte, R. M., Dobslaw, H., & Salstein, D. A. (2021). Convergence of daily GRACE solutions and models of submonthly ocean bottom pressure variability. Journal of Geophysical Research: Oceans, 126, e2020JC017031. https://doi.org/10.1029/2020JC017031

Contents:

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

  1. DEBOT (David Einspigel Barotropic Ocean Tide Model): 1/3° horizontal grid spacing, single-layer model
  2. 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)
