Abstract:

The 1-km/daily Evapotranspiration Dataset over Heihe River Basin in China (2000-2015) was developed using the evapotranspiration estimation model ETMonitor. The model considers land surface energy balance, water transfer and vegetation physiological processes, and is driven by a variety of biophysical parameters derived from multi-source remote sensing data. In order to fully consider the response of evapotranspiration to soil moisture conditions, a three-layer soil water transport model is added to ETMonitor, and the Ensemble Kalman Filter (EnKF) data assimilation method is used to improve the simulation effect of soil moisture conditions. The coordinate system of the dataset is latitude-longitude, the spatiotemporal resolution is 0.01°/1-day, and the spatial coverage is 96.5°E-102.5°E, 37.5°N-43°N. The dataset is archived daily, and the data format is ENVI standard. The data type is single precision floating point, and the unit is mm/day. The size of annual data is 460 MB, and the total data size is 7.2 GB (compressed to 16 files with 5.37 GB).
