Fig. 3. Seasonal variations in energy balance ratio (EBR)(A), mean month air temperature (Ta)(B), vapor press deficit (VPD)(C), soil water content (SWC)(D) at 0-10 cm soil depth and Albedo (E) across different sites in Nei Mongol grasslands. The shallow green shaded area in the graph represents the growing season period (April to September). DL, EG, SZ, XL1, XL2 and XW represent Duolun site, Ergun site, Siziwangqi site, Xilinhot mowed site, Xiwuqi fenced site and Xi Ujimqin Qi site, respectively.
