A very comprehensive analysis of lagged precipitation effects in terrestrial ecosystems. Tree rings, flux, grassland ANPP, satellite remote sensing, and DGVMs. Climate memory is an important driver of global plant productivity.
He ert al. integrate ground-based observations, remote sensing and process-based models to disentangle the relative contribution of preceding-year and current-year precipitation on plant productivity and identify its predictors across biomes
