Effects of Air Temperature and Precipitation on Soil Moisture on the Qinghai-Tibet Plateau during the 2015 Growing Season

Table 1

Correlations between precipitation and SM through the soil profile at Naqu.

		Precipitation	10 cm	20 cm	30 cm	40 cm
10		0.61
20		0.34	0.77
30		0.16	0.43	0.82
40		0.12	0.28	0.68	0.95
50		0.1	0.23	0.62	0.88	0.97

∗∗ and ∗∗ indicate that the correlation coefficients are statistically significant at the 99% and 99.9% levels, respectively (Student’s t-test).
