Fig. 4 — Flux tower data from three sites (K34, K67, and BAN) in Amazonia showing the mean climatology of GPP normalized by the ratio of leaf internal CO₂ partial pressure (c_i) to atmospheric CO₂ partial pressure (c_a) (A, C, and E). Remote sensing data for these same three sites showing the mean climatology of SIF and VPD (B, D, and F). Daytime data (averaged from hourly data with no precipitation) are used for varying time periods between 2002 and 2006 based on data availability for the flux tower data. For remote sensing data, monthly data from June 2007 to May 2016 are used.
