Simulating the Energy and Water Fluxes from Two Alkaline Desert Ecosystems over Central Asia

Figure 6

Taylor diagram plot of the simulated (a), (b), (c), and (d) computed from a reference model (S0) and six independent sensitivity tests (S2–S7, see Table 3) from the CoLM against EC observations at the two EC sites. Standard deviation (STD, W m⁻²) is calculated as the simulated variables divided by the observed data. “Obs” refers to observed data points. Root mean square error (RMSE, W m⁻²) is represented by green lines. is the correlation coefficient. The higher the and the smaller the STD and RMSE, the better the agreement between model and data. When comparing two simulations with different parameter values, the longer the distance between the two simulation points, the greater the sensitivity to that parameter.
