Extended Data Fig. 3: Partial effect surfaces and residual autocorrelation for half-hourly GAMMs.
From: Widespread influence of artificial light at night on ecosystem metabolism
Final weighted half-hourly GAMMs for a, b) NEE, c, d) GPP and e, f) Re are shown. Partial effect surfaces (a, c, e) display the estimated tensor-product smooth interaction between ALAN and night duration, as derived from the final GAMMs in Supplementary Table 5. Panels b, d and e show partial autocorrelation functions of the model residuals (at hourly lags), indicating the degree of remaining temporal autocorrelation after model fitting. Dashed blue lines represent approximate 95% confidence intervals for the null hypothesis of white noise.
