title: Source data for graphs and charts in Rivoire, L., Curbelo, J., and Linz, M., 2026, Tracking jet streams as Lagrangian objects, Commun. Earth Environ.

description: <b>This dataset provides the s</b><b>ource data needed to reproduce graphs and charts for the</b><b> four figures found in the main text of: </b><b>Rivoire, L., Curbelo, J., and Linz, M., 2026, Tracking jet streams as Lagrangian objects, Commun. Earth Environ.</b>Each file corresponds to a figure in the paper. Files are in MATLAB's native .mat format, produced with MATLAB 23.2.0.2485118 (R2023b) Update 6. See the documentation: https://www.mathworks.com/help/matlab/import_export/mat-file-versions.html. To read the files with Python:<br>from scipy.io import loadmatdata = loadmat('fig_1.mat')<br><br>All variables are given descriptive names, including which panel they correspond to in the figures. For example, in fig_1.mat, variable 'jet_left_panel_B' provides the jet axis for the left side of panel B. In fig_4.mat, variable 'KDE_F' is a MATLAB structure (for Python users, analogous to a list of dictionaries whose values are NumPy arrays) and provides the estimated probability density values for the corresponding x-values (the latitude or wind speed grid) in 'KDE_XF'. Within the structures, data for the Eulerian "wind-based" method are denoted with "W", data for the Lagrangian method are denoted with "M" (the "M" function), and data for the Eulerian "theta-based" method are denoted with "PT" (theta is Potential Temperature). See the full detail of variables and attributes at the end of this document.<br>Data from figure 2 panel C are not provided and can be more efficiently reproduced using equation (2) in the paper. This dataset is intended solely for figure reproduction and does not include the full underlying analysis pipeline or raw input data. All physical quantities use the same units and conventions as in the published figures (e.g., latitude in degrees, wind speed in m/s). Missing values are represented as NaNs.<br>Also see the full JetLag dataset: 10.5281/zenodo.16178219<br><br><b>Full detail of variables and attributes:</b><br><b>fig_1.mat</b><br> jet_extra 17x360 48960 double jet_left_panel_B 1x360 2880 double <br> jet_left_panel_C 1x360 2880 double <br> jet_lon 1x360 2880 double <br> jet_right_panel_B 1x360 2880 double <br> jet_right_panel_C 1x360 2880 double <br> time_left_panel_B - 8 datetime <br> time_left_panel_C - 8 datetime <br> time_right_panel_B - 8 datetime <br> time_right_panel_C - 8 datetime <br> trajlat_1_panel_B 48x1 384 double <br> trajlat_1_panel_C 36x1 288 double <br> trajlat_2_panel_B 48x1 384 double <br> trajlat_2_panel_C 36x1 288 double <br> trajlon_1_panel_B 48x1 384 double <br> trajlon_1_panel_C 36x1 288 double <br> trajlon_2_panel_B 48x1 384 double <br> trajlon_2_panel_C 36x1 288 double <br> wind_lat 721x1 5768 double <br> wind_left_panel_B 1440x721 8305920 double <br> wind_left_panel_C 1440x721 8305920 double <br> wind_lon 1440x1 11520 double <br> wind_right_panel_B 1440x721 8305920 double <br> wind_right_panel_C 1440x721 8305920 double <br><br><b>fig_2.mat</b><br> M 181x360x6 3127680 double <br> jet_eulerian 1x360 2880 double <br> jet_lagrangian_mat 5x360 14400 double <br> jetlat_jetlag_DJF 1x13 104 double <br> jetlat_jetlag_JJA 1x13 104 double <br> jetlat_wind_DJF 1x7 56 double <br> jetlat_wind_JJA 1x7 56 double <br> jetlatstd_jetlag_DJF 1x13 104 double <br> jetlatstd_jetlag_JJA 1x13 104 double <br> jetlatstd_wind_DJF 1x7 56 double <br> jetlatstd_wind_JJA 1x7 56 double <br> lat_out 1x181 1448 double <br> lon_out 1x360 2880 double <br> t_start 1x1 8 double <br> tau_panel_B 1x6 48 double <br> tau_panel_D 1x13 104 double <br><b>fig_3.mat</b><br> PSD_jetlag 1x58440 467520 double PSD_theta 1x58440 467520 double <br> PSD_wind 1x58440 467520 double <br> hov_jetlag_DJF 364x360 1048320 double <br> hov_jetlag_JJA 368x360 1059840 double <br> hov_wind_DJF 364x360 1048320 double <br> hov_wind_JJA 368x360 1059840 double <br> lat_jetlag 7309x1 58472 double <br> lat_theta 7309x1 58472 double <br> lat_wind 7309x1 58472 double <br> period 1x58440 467520 double <br> speed_jetlag 7309x1 58472 double <br> speed_theta 7309x1 58472 double <br> speed_wind 7309x1 58472 double <br> time - 116896 datetime <br> time_DJF - 2912 datetime <br> time_JJA - 2944 datetime <br><br><b>fig_4.mat</b><br> KDE_F 1x1 18528 struct <br> KDE_XF 1x1 18528 struct <br> jetfreq_diff_stj 180x360 518400 double <br> jetfreq_jetlag_pfj 180x360 518400 double <br> jetfreq_jetlag_stj 180x360 518400 double <br> jetfreq_wind_stj 180x360 518400 double <br> lat 1x180 1440 double <br> lon 1x360 2880 double <br>
