This dataset contains NOAA GFDL's ESM4.1 outputs for the California Current System interpolated to 1˚ latitude/longitude resolution and a netCDF file containing data from Argo float 7647. The jupyter notebook files are examples of how to run eOMP analysis using these data and the pyompa scripts described in Shrikumar et al. (2022). The Argo float data does not include phosphate and silicate, which were not measured. These variables are estimated using ESPER routines (Carter et al., 2021) as described in the matlab file.
