  abstract = {{T}he {ECO}system {S}paceborne {T}hermal {R}adiometer {E}xperiment on {S}pace {S}tation ({ECOSTRESS}) is a scientific mission that collects high spatio-temporal resolution (similar to 70 m, 1-5 days average revisit time) thermal images since its launch on 29 {J}une 2018. {A}s a predecessor of future missions, one of the main objectives of {ECOSTRESS} is to retrieve and understand the spatio-temporal variations in terrestrial evapotranspiration ({ET}) and its responses to soil water availability and atmospheric aridity. {I}n the {E}uropean {ECOSTRESS} {H}ub ({EEH}), by taking advantage of land surface temperature ({LST}) retrievals, we generated {ECOSTRESS} {ET} products over {E}urope and {A}frica using three models with different structures and parameterization schemes, namely {S}urface {E}nergy {B}alance {S}ystem ({SEBS}) and {T}wo {S}ource {E}nergy {B}alance ({TSEB}) parametric models, as well as the non-parametric {S}urface {T}emperature {I}nitiated {C}losure ({STIC}) model. {A} comprehensive evaluation of the {EEH} {ET} products was conducted with respect to flux measurements from 19 eddy covariance sites in {E}urope over six different biomes with diverse aridity levels. {R}esults revealed comparable performances of {STIC} and {SEBS} ({RMSE} of similar to 70 {W} m(-2)). {H}owever, the relatively complex {TSEB} model produced a higher {RMSE} of similar to 90 {W} m(-2). {C}omparison between {STIC} {ET} estimates and the operational {ECOSTRESS} {ET} product from {NASA} {PT}-{JPL} model showed a larger {RMSE} (around 50 {W} m(-2) higher) for the {PT}-{JPL} {ET} estimates. {S}ubstantial overestimation (>80 {W} m(-2)) in {PT}-{JPL} {ET} estimates was evident over shrublands and savannas, presumably due to weak constraint of {LST} in the model. {O}verall, the {EEH} supports {ET} retrieval for the future high-resolution thermal missions.},
