Implied heat transport from Top of Atmosphere fluxes#
This recipe calculates the implied horizontal heat transport (IHT) due to the spatial anomalies of radiative fluxes at the top of the atmosphere (TOA). The regional patterns of implied heat transport for different components of the TOA fluxes are calculated by solving the Poisson equation with the flux components as source terms. It reproduces the plots in Pearce and Bodas-Salcedo (2023) when the input data is CERES EBAF.
Available recipes and diagnostics#
Recipes are stored in esmvaltool/recipes/
recipe_iht_toa.yml calculates the IHT maps for the following radiative fluxes:
Total net, SW net, LW net (Figure 2).
Total CRE, SW CRE, LW CRE (Figure 4).
All-sky and clear-sky reflected SW (Figure 5).
The meridional heat transports (MHT) of the fluxes above (Figures 1 and 3).
Diagnostics are stored in esmvaltool/diag_scripts/iht_toa/
single_model_diagnostics.py: driver script that produces the plots.
poisson_solver.py: solver that calculates the IHTs.
