Trajectories were calculated both from the ship's position and within a circle with origo at the ship and a radius of 100 km.\r\n\r\nTrajectories from the ship position were initialised every 1-hour. Trajectories from within a circle were initialised every 6-hour at locations 30 km equidistant from each other. All trajectories were initialised at 14 different vertical starting levels. The trajectories were calculated with the Lagrangian Analysis Tool LAGRANTO on ERA5 data \u2014 fifth generation of ECMWF atmospheric reanalysis data.\r\n\r\nThis dataset contains the raw native data for all of the four different sets of trajectory runs. Data tracked and calculated along the tracks by the trajectory model, e.g., longitude, latitude, pressure, temperature and relative humidity, are included. Four associated user-friendly datasets, with additional surface variables interpolated along the tracks but reduced to 7-day trajectories, are available separately for each set of trajectory run.\r\n\r\nThe data enable analysis of air mass origin and air mass transformation of air parcels starting or ending up at and around Oden during the ARTofMELT expedition in the Arctic spring of 2023.","url":"http:\/\/bolin.su.se\/data\/oden-artofmelt-2023-trajectories-raw-1","keywords":["Atmosphere","Circulation","Air parcel trajectories","Arctic","Arctic Ocean","Meteorology","LAGRANTO","ARTofMELT","ARTofMELT 2023 expedition","Icebreaker Oden","Earth science > Atmosphere"],"creator":{"@type":"Person","name":"Sonja Murto, Michael Tjernstr\u00f6m"},"citation":"Murto S, Tjernstr\u00f6m M (2024a) Backward trajectories along the ship track using the LAGRANTO model, for the expedition ARTofMELT, Arctic Ocean, 2023.
