Summary: | Copyright information: Taken from "Spectral measures and mixed models as valuable tools for investigating controls on land surface phenology in high arctic Greenland"http://www.biomedcentral.com/1472-6785/7/9BMC Ecology 2007;7():9-9.Published online 19 Sep 2007PMCID:PMC2164935.the GAMM model to calculate the additive contribution of each variable using non parametric smoothing methods. Thus, the y-axis can be interpretted as a transformation of SINDVI. Low values on the y-axis correlate with low SINDVI, while high values correlate with higher SINDVI. Dashed lines indicate twice standard errors. Each short bar on the x-axis indicates an observation. A: End of snow melt, B: summed air temperature during the growing season, C: summed PAR during the growing season, D: summed rain during the growing season, E: seasonal integrated NDVI-FR in the previous growing season, F: summed air temperature during the previous growing season. Estimated degrees of freedom are shown by each Y-axis. |
