Leave-one-site-out validation for GPP (a), RECO (b) and NEE (c). Red: R2 ≥ 0.75; Yellow: 0.5 ≤ R2 < 0.75; Cyan: 0.25 ≤ R2 < 0.5; Blue: R2 < 0.25. For GPP, the percentage of sites is 62% (red), 24% (yellow), 8% (cyan), and 6% (blue). For NEE, the percentage is 23% (red), 27% (yellow), 27% (cyan), and 23% (blue).
