Figure 1. The distributions of (a) viewing zenith angle (VZA) and (b) SIF from OCO-2, and (c) the relationships between GPP and OCO-2 SIF from 82 tower sites in different modes (nadir, blue; glint, red; target, black). The SIF at different VZA for (d) US-PFa (mixed forest), (e) AU-How (woody savannas), and (f) FI-Hyy (evergreen needleleaf forest) sites. Each point is binned in a specific range of VZA. For example, the SIF at VZA of 30° is the mean of all SIF values at VZA of 25-35°. The relationships with an intercept between SIF and GPP under different VZA for (g) US-PFa, (h) AU-How, and (i) FI-Hyy sites. The relationships without an intercept between SIF and GPP under different VZA for (j) US-PFa, (k) AU-How, and (l) FI-Hyy sites.



Figure 2. The viewing zenith angle of nadir (blue circles) and glint modes (red circles) for (a) US-SRM (woody savannas), (b) AU-Stp (grass), and (c) US-GLE (evergreen needleleaf forest) sites. The relationships between OCO-2 SIF and GPP for nadir (blue circles) and glint modes (red circles) at (d) US-SRM, (e) AU-Stp, and (f) US-GLE sites. The slopes were compared using two-tailed T test for individual site.
