This dataset includes time-averaged and instantaneous velocity, temperature, and streamfunction fields associated with the Direct Numerical Simulation of a single-box idealized and laboratory-scale ocean model representing the North Atlantic Ocean. The dataset comprises two-dimensional and three-dimensional data, enabling users to replicate all the figures shown in the JGR ocean paper "Three-Dimensional Ocean Circulation: Analyzing Wind and Deep Convection with Turbulence-Resolving Simulations." A one-dimensional Excel file for reproducing transport plots is also available. The data format is netCDF, which provides easy access and readability. The simulation contains various wind parameter S and buoyancy forcing, Rayleigh number, as indicated in the file names. The time-averaged fields are averaged over 200 buoyancy time scales.
