Supporting datasets and ensemble members/submembers for the PASTEL model. Brief description of individual entries: v0_1_5_Awakens.csv — A merged dataset combining multiple airborne campaigns with supplementary 24-hour backward trajectory information. Represents the input samples used to train PASTEL. Koppen_npy_files.zip — Numpy arrays containing merged land (Beck et al. 2023) and ocean (Walterscheid 2011) Köppen climate classifications at 0.5° x 0.5° global resolution. Includes a Matplotlib colormap (Python .pkl), following Beck et al. (2023), along with alternative Köppen representations. worldcities.zip — Simplemaps basic dataset (see attribution and license within). df_preprocessed.csv — A preprocessed version of v0_1_5_Awakens.csv containing additional derived features and statistics. Can be used to bypass preprocessing steps in the main PASTEL notebook. AllTrajectories.zip — All 24-hour backward HYSPLIT trajectories generated for each sample in v0_1_5_Awakens.csv and df_preprocessed.csv, with varying meteorological inputs (see associated publication for details). ne_10m_land.zip — Natural Earth shapefile containing 10-meter resolution land boundaries. ERA5_32yr_monthly_avg.nc — NetCDF file containing 32-year monthly averages of ERA5 data (ozone, specific humidity, relative humidity, temperature) over the study period. ensemble.zip — Ensemble members and submembers contributing to PASTEL predictions, along with derived statistics and plots (≈27 GB uncompressed).

Size Warning "ensemble.zip" is roughly 27GB uncompressed as statistics/plotting information for all members/submembers is included!
