Figure 6From: Spectral measures and mixed models as valuable tools for investigating controls on land surface phenology in high arctic GreenlandRelationship between NDVI-FR and NDVI. Each data point is marked by a letter indicating the vegetation type for that plot measurement. C: Cassiope heath, D: Dryas heath, F: Fen, G: Grassland, S: Salix heath. The linear relation is shown in solid (R2 = 0.79, n = 390, p < 0.0001) and the 1:1 line in dashed.Back to article page
