Long-Term (2007 to 2018) Energy and CO2 Fluxes over an Agriculture Ecosystem in the Southeastern Margin of the Tibetan Plateau
Table 4
Correlation coefficients of the averaged sensible heat flux (Hs) and environmental variables including the averaged wind speed (WS) at 4 m height, temperature difference between the upper soil layer (at 4 cm depth) and the atmosphere (ΔT), the WS multiplied by ΔT (WS ΔT), net radiation (Rn) at 1.5 m height, air temperature (Ta), the total precipitation (PPT), and the normalized difference vegetation index (NDVI) at multiple timescales from 2007 to 2018. There is no examination about the PPT at half-hourly timescales and the NDVI between half-hourly and daily timescales.
