  abstract = {{T}he {ECO}system {S}paceborne {T}hermal {R}adiometer {E}xperiment on {S}pace {S}tation ({ECOSTRESS}) was launched to the {I}nternational {S}pace {S}tation on 29 {J}une 2018 by the {N}ational {A}eronautics and {S}pace {A}dministration ({NASA}). {T}he primary science focus of {ECOSTRESS} is centered on evapotranspiration ({ET}), which is produced as {L}evel-3 ({L}3) latent heat flux ({LE}) data products. {T}hese data are generated from the {L}evel-2 land surface temperature and emissivity product ({L}2_{LSTE}), in conjunction with ancillary surface and atmospheric data. {H}ere, we provide the first validation ({S}tage 1, preliminary) of the global {ECOSTRESS} clear-sky {ET} product ({L}3_{ET}_{PT}-{JPL}, {V}ersion 6.0) against {LE} measurements at 82 eddy covariance sites around the world. {O}verall, the {ECOSTRESS} {ET} product performs well against the site measurements (clear-sky instantaneous/time of overpass: r(2) = 0.88; overall bias = 8%; normalized root-mean-square error, {RMSE} = 6%). {ET} uncertainty was generally consistent across climate zones, biome types, and times of day ({ECOSTRESS} samples the diurnal cycle), though temperate sites are overrepresented. {T}he 70-m-high spatial resolution of {ECOSTRESS} improved correlations by 85%, and {RMSE} by 62%, relative to 1-km pixels. {T}his paper serves as a reference for the {ECOSTRESS} {L}3 {ET} accuracy and {S}tage 1 validation status for subsequent science that follows using these data. {K}ey {P}oints {ECOSTRESS} is a state-of-the-art combination of thermal bands, spatial and temporal resolutions, and measurement accuracy and precision {D}ata from 82 eddy covariance sites were coalesced concurrently with the first year of {ECOSTRESS} for {S}tage 1 validation {C}lear-sky {ET} from {ECOSTRESS} compared well against a wide range of eddy covariance sites, vegetation classes, climate zones, and times of day},
