Heat-transport-spatial-decomp-POP

MATLAB codes to compute the meridional heat transport and its spatial-scale decomposition, configured for POP simulations (ocean component of CESM) on a tripole grid.

These scripts and functions were used to generate the figures in two publications. The primary scripts used to generate each figure are listed below.

POP_lat_transects_extract.m – MATLAB function (to be used on each file timestep) to extract latitude transects within specified ranges, and generate a .mat file of v and T along each transect

Figure 3: Run POP_heat_transport_multitransects_fromtrfile.m to generate .mat files with heat transport components, then run POP_spat_decomp_plots.m to plot.

Figure 1: EKE_map_altimetry.m and EKE_mean_map_global_POP.m

POP_lat_transects_extract.m was run to generate .mat file of v and T along each integer latitude, then POP_heat_transport_multitransects_fromtrfile.m to generate .mat file with temperature flux components (with names of the form Multitransect_arrays_POP_IndoPac_1deg.mat, where "IndoPac" is the basin name; other basin names include "Atl" and "South").
