Hoffman, Lauren; Mazloff, Matthew R.; Gille, Sarah T.; Giglio, Donata (2021). Data from: Ocean Surface Salinity Response to Atmospheric River Precipitation in the California Current System. UC San Diego Library Digital Collections. https://doi.org/10.6075/J0BV7GGW

With the goal of understanding the ocean's surface salinity response to precipitation from atmospheric rivers, these data include oceanic values for salinity and temperature; and atmospheric values of precipitation, wind speed, specific humidity, air temperature, and long and shortwave radiation.

The file contains data from five different data sources:
(1) European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis (ERA5);
(2) Scripps Institution of Oceanography (SIO)-generated AR catalog, the SIO-R1 AR catalog;
(3) California Underwater Glider Network (CUGN) Spray Glider along Line 66.7;
(4) Monterey Bay Aquarium Research Institute (MBARI) M1 Mooring;
(5) Modeled outputs from a one-dimensional configuration of the Massachusetts Institute of Technology General Circulation Model (MITgcm);

Several steps were taken to process the data to produce various figure and model inputs. The files and descriptive file paths for these are included here.
