Improving the Performance of Temperature Index Snowmelt Model of SWAT by Using MODIS Land Surface Temperature Data

Table 8

Performance of Elev𝑇_𝑎 and New𝑇_𝑎 scenarios in the least parameters and complete parameters settings.

Basin	The least parameters settings				Complete parameters setting
	Elev𝑇𝑎		New𝑇𝑎		Elev𝑇𝑎		New𝑇𝑎
	𝑅^2	NSE	𝑅^2	NSE	𝑅^2	NSE	𝑅^2	NSE
A	0	−0.88	0.15	0.15	0.22	0.11	0.42	0.42
B	0	−3.98	0.19	−0.51	0.43	0.29	0.57	0.49
C	0.67	0.63	0.75	0.73	0.79	0.72	0.79	0.75

Elev𝑇_𝑎 scenario is elevation bands combined with the original monitoring air temperature data scenario, and New𝑇_𝑎 scenario is the newly created air temperature data. 𝑅² is coefficient of determination, and NSE is Nash-Sutcliffe efficiency.
