Chen, Ru; McClean, Julie L.; Gille, Sarah T.; Yulaeva, Elena; Ivanova, Detelina P.; Cerovečki, Ivana (2021). Data from: Effect of atmospheric forcing resolution on simulated mixed layer depth in the North Pacific. UC San Diego Library Digital Collections.


This dataset contains daily output from two numerical simulations in the North Pacific domain, using the 0.1 degree Parallel Ocean Program (POP) model in the Community Climate System Model 4 framework. The atmospheric forcing in the first simulation is taken from a 0.6 degree resolution Weather Research and Forecasting (WRF) simulation, and the forcing in the second simulation is the low-pass filtered forcing used in the first experiment. Therefore, these two simulations would be valuable for potential studies evaluating the role of mesoscale atmospheric forcing on the physical state of the ocean (e.g. circulation, sea surface height and mixed layer conditions).

Scope And Content

This dataset includes forcing variables (wind stress, heat flux, and virtual salt flux), surface variables (velocities, sea surface height, temperature and salinity), mixed layer depth, boundary layer depth, etc. File names distinguish between the two sets of model runs. NPRC=North Pacific Regional Configuration; hb3=unsmoothed winds; sm4=smoothed winds, with smoothing intended to suppress high-wavenumber structures that are not included in Coordinated Ocean-ice Reference Experiments-II (CORE-II) forcing.

The two original data files released here in 2021 contained the two model outputs, NPRC_WRF06_hb3 and NPRC_WRF06_sm4. On 2023-04-06, the model outputs were rebundled into smaller components, each containing 3 months of daily fields. In addition, the following data were added: unfiltered atmospheric forcing from WRF, filtered atmospheric forcing from WRF, ocean model grid variables, and lists of variables for each data type.
