Description

This dataset contains a subset from a dataset of 14-day back trajectories released from points along the ocean drainage basin catchment boundaries used in Craig, P. et al. (2023).

Six-hourly data from the ERA-Interim re-analysis from the European Centre for Medium Range Weather Forecasts (Dee et al., 2011) and the ROTRAJ model code (https://www.met.reading.ac.uk/~swrmethn/ROTRAJ/) were used to generate the back trajectories. Data were released every 12 hours on 17 vertical levels. The full dataset covers the years 2010-14 and contains 20.3 million trajectories per year.

The dataset defining the ocean catchment boundaries is available from the University of Reading Research Data Archive (https://doi.org/10.17864/1947.195).

The back trajectories can be read using the Python code readtraj_example.py provided here.
