Coupled vegetation-precipitation variability observed from satellite and climate records
Open accessAbstract
Variability in precipitation regimes at seasonal and longer time scales strongly influences ecosystem dynamics in arid and semi‐arid regions. In this paper, we use time series of global precipitation and satellite normalized difference vegetation index (NDVI) data to analyze joint spatial and temporal variability between terrestrial ecosystems and precipitation regimes. Accumulated monthly rainfall anomalies are quantified using a standardized precipitation index (SPI), which provides a better measure of ecologically significant precipitation excess or deficit at growing season time scales relative to monthly precipitation data. Results from canonical correlation analysis reveal geographically extensive patterns of joint NDVI‐SPI variability suggestive of strong climate‐biosphere coupling. Further, leading modes of covariability are shown to be related to large‐scale ocean‐atmosphere circulation anomalies. These results illustrate the global extent and sensitivity of ecosystems susceptible to climate change‐induced perturbations in precipitation regimes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
