Terrestrial evapotranspiration dataset across China

This terrestrial evapotranspiration dataset is derived from the complementary-relationship method, with inputs of CMFD downward short- and long-wave radiation, air temperature, humidity, air pressure, GLASS albedo and broadband longwave emissivity, MODIS LST, and NCEP diffuse skylight ratio. This dataset covers the period of 1982-2015 with spatial and temporal resolutions of 0.1-degree and monthly, respectively.  This dataset would be helpful for long-term hydrological cycle and climate change research.

 This terrestrial evapotranspiration dataset is derived from the complementary-relationship (CR) method of Szilagyi et al.  (2017, A calibration-free formulation of the complementary relationship of evaporation for continental-scale hydrology. Journal of Geophysical Research: Atmospheres, 122, doi: 10.1002/2016jd025611). The inputs of the model include net radiation, wind speed, air and dew-point temperature from a wide range of data sources. Please also refer the reference of the dataset for details. 

This evapotranspiration dataset is only for land surface.

Research for use:Hydrological cycle, land surface processes and climate change research.
