Detected, categorised and tracked jets, diverse quantities interpolated in jet-centred coordinates

`all_jets_one_df.parquet`: detected jet cores in the North Altantic and European sector. Contains the categorisation information with the column 'is_polar'. `cross_catd.parquet` and `jet_persistence.parquet`: Jet tracking output, from the function `jetutils.jet_finding.track_jets()`. A row for each day and jet, columns have various intermediate tracking results but mainly the Frechet distance between the two jets and their longitudinal overlap. `props_as_df_uncat.parquet` and `props_as_df.parquet`. Jet properties as described in Banderier et al. 2025. Uncategorised (one row per time and jet core) and categorised (one row per time and jet category), respectively. `cluster_df.nc`: Heat waves regions from Pappert et al. 2025 `region_t2m_dailymean_anom.parquet` and `region_tp_dailymean_anom.parquet`. Regionalised temperature and precipitation daily anomalies in the regions defined by `cluster_df.nc` `jet_centred` directory: interpolated fields on the jet-centred plane. Everything is at daily temporal resolution. For eddy quantities, eddies are separated from the mean flow using a 10-day high-pass filter on the dataset of zonal and meridional wind at 250 hPa. APVO and CPVO: Anticyclonic and Cyclonic PV Overturning, detected using the wavebreaking package 10.5281/zenodo.14214463. EKE250: Eddy Kinetic Energy at 250 hPa. EMFconv250: Eddy Momentum Flux convergence at 250 hPa. PV330: Potential Vorticity on the 330K isentrope. PV350: Potential Vorticity on the 350K isentrope.
