Modeling ocean heat transport to the grounding lines of Pine Island, Thwaites, Smith, and Kohler glaciers, West Antarctica

# Particle trajectories advected using outputs from the Southern Ocean high-resolution (SOhi) simulation for Pine Island, Thwaites, Smith, and Kohler glaciers ## Description of the data and file structure Particle trajectories for each of the four glaciers (Pine Island, Thwaites, Smith, and Kohler) is stored in their own corresponding zipped -.zarr format. Unzipped the folder and the zarr store can be accessed with python using: > import zarr > > dataset = zarr.open('path/to/file.zarr', mode='r') > > var_data = dataset['var_name'] Replace 'var_name' with the variable of interest. The available variables are: **Dimensions** `obs` : Observation ID `trajectory` : Particles ID **Data Variables** (dimension = trajectory x obs): `age` : Age of particle (in seconds), starting from when the particles are initialized `time` : Time of particle (in seconds) with respect to the velocity fields. Particles with the same time is advected using the same fields. `lat` : Latitude (-90 to 90) of particle `lon` : Longitude (-180 to 180) of particle `z` : Depth of particle (meters) `salinity` : Salinity sampled from SOhi outputs (psu) `temperature` : Potential temperature sampled from SOhi outputs (C) Note that the last few timesteps are filled with nan and does not contain any data. This is due to a mismatch between the prescribed chunk size and the total run time. Note that the stuck particles (particles advected into a dry cell) have not been removed from the dataset. These particles should be filtered and removed during analysis.
