This dataset contains the model output used for the analysis described in "Site-specific multiple stressor assessments based on high frequency surface observations and an Earth system model" article, accepted for publication in Earth and Space Science. The manuscript presents comparisons of modeled chemical and biological variables to observations from autonomous moorings at daily frequency. The comparisons were carried out in the context of diagnosis of temperature and ocean acidification extreme events. The locations of daily model output time series included in this dataset match the CO2 mooring time series of Sutton et al. (2019). The code used to extract the data archived here as well as for the analyses presented in the associated manuscript is available in a GitHub repository and archived through Zenodo (see README.txt file in the data archive).
