HYSPLIT Trajectories during MARCUS 2017/2018

This dataset contains the raw output of the HYSPLIT trajectory model, run for the ship’s location for every hour of the MARCUS campaign aboard the resupply voyages of the Aurora Australis, 2017/18 season. \nLineage: Trajectories were run for five days backwards in time, beginning at four altitudes above sea level: 10, 100, 500 and 2000 m. The Global Data Assimilation (GDAS) reanalysis dataset was used to drive the model, using the 1 degree horizontal resolution. Vertical motion utilized the model vertical velocity method. Calculations utilized surface invariant geopotential, surface 10 m horizontal (U and V) winds, 2 m surface temperature, and U, V, W (vertical wind), temperature and humidity on pressure levels from 1000 to 20 hPa.
