Long-Term (2007 to 2018) Energy and CO₂ Fluxes over an Agriculture Ecosystem in the Southeastern Margin of the Tibetan Plateau

Table 5

Similar to Table 4, the flux variable is the latent heat flux (LE), and the environmental variables include the WS, Rn, Ta, PPT, NDVI, as well as the vapor pressure deficit (VPD), and the WS multiplied by VPD (WS  VPD) at 4 m height.
