Fig. 6 — Partial correlation coefficient (R) between detrended annual R_s and detrended driving factors are shown in (A) R_s and TEM, (B) R_s and PRE, (C) R_s and SPEI, (D) R_s and TC cover, (E) R_s and SV cover, and (F) R_s and BG cover. R = ±0.64, R = ±0.51, R = ±0.44, R = ±0.35, and R = ±0.19 correspond to the 0.01, 0.05, 0.1, 0.2, and 0.5 significance levels, respectively. To reduce the effects from the data acquisition error in the land-cover data, only the per-pixel percent cover of TC, SV, and BG greater than 25% (61) was used to conduct the partial correlation analysis.
