  abstract = {{E}vapotranspiration and energy partitioning are complex to estimate because they result from the interaction of many different processes, especially in multi-species and multi-strata ecosystems. {W}e used {MAESPA} model, a mechanistic, 3{D} model of coupled radiative transfer, photosynthesis, and balances of energy and water, to simulate the partitioning of energy and evapotranspiration in homogeneous tree plantations, as well as in heterogeneous multi-species, multi-strata agroforests with diverse spatial scales and management schemes. {T}he {MAESPA} model was modified to add (1) calculation of foliage surface water evaporation at the voxel scale; (2) computation of an average within-canopy air temperature and vapour pressure; and (3) use of (1) and (2) in iterative calculations of soil and leaf temperatures to close ecosystem-level energy balances. {W}e tested {MAESPA} model simulations on a simple monospecific {E}ucalyptus stand in {B}razil, and also in two complex, heterogeneous {C}offea agroforests in {C}osta {R}ica. {MAESPA} satisfactorily simulated the daily and seasonal dynamics of net radiation ({RMSE} = 29.6 and 28.4 {W} m(-2); {R}-2 = 0.99 and 0.99 for {E}ucalyptus and {C}offea sites respectively) and its partitioning between latent-({RMSE} = 68.1 and 37.2 {W} m(-2); {R}-2 = 0.87 and 0.85) and sensible-energy ({RMSE} = 54.6 and 45.8 {W} m(-2); {R}-2 = 0.57 and 0.88) over a one-year simulation at half-hourly time-step. {A}fter validation, we use the modified {MAESPA} to calculate partitioning of evapotranspiration and energy between plants and soil in the above-mentioned agro-ecosystems. {I}n the {E}ucalyptus plantation, 95% of the outgoing energy was emitted as latent-heat, while the {C}offea agroforestry system's partitioning between sensible and latent-heat fluxes was roughly equal. {W}e conclude that {MAESPA} process-based model has an appropriate balance of detail, accuracy, and computational speed to be applicable to simple or complex forest ecosystems and at different scales for energy and evapotranspiration partitioning.},
