abstract = {The ECOsystem Spaceborne Thermal Radiometer Experiment on
Space Station (ECOSTRESS) was launched to the International
Space Station on 29 June 2018 by the National Aeronautics
and Space Administration (NASA). The primary science focus
of ECOSTRESS is centered on evapotranspiration (ET), which
is produced as Level‐3 (L3) latent heat flux (LE) data
products. These data are generated from the Level‐2 land
surface temperature and emissivity product $(L2_LSTE),$ in
conjunction with ancillary surface and atmospheric data.
Here, we provide the first validation (Stage 1, preliminary)
of the global ECOSTRESS clear‐sky ET product
$(L3_ET_PT‐JPL,$ Version 6.0) against LE measurements at
82 eddy covariance sites around the world. Overall, the
ECOSTRESS ET product performs well against the site
measurements (clear‐sky instantaneous/time of overpass: r2
= 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. The
70‐m‐high spatial resolution of ECOSTRESS improved
correlations by $85\%,$ and RMSE by $62\%,$ relative to
1‐km pixels. This paper serves as a reference for the
ECOSTRESS L3 ET accuracy and Stage 1 validation status for
subsequent science that follows using these data.},
