Modelling of Water Surface Temperature of Three Lakes on the Tibetan Plateau using a Physically Based Lake Model

Figures & data

Fig. 1 Geographical distribution of the lakes on the TP. (a) Nam Co, (b) Zhaling Co, and (c) Lake Qinghai.

Fig. 2 Initial results of the simulations for the three lakes. The red line is the simulated WST (°C) and the black line shows the MODIS data for (a) Lake Qinghai, (b) Zhaling Co, and (c) Nam Co.

Table 1. RMSEs and CORs of Lake Qinghai, Zhaling Co, and Nam Co.

	Lake Qinghai	Zhaling Co	Nam Co
RMSE (°C)	3.8	3.2	5.0
COR	0.96	0.95	0.90
