The climatic drivers of normalized difference vegetation index and tree-ring-based estimates of forest productivity are spatially coherent but temporally decoupled in Northern Hemispheric forests

Popis výsledku v původním jazyce

Aim Radial growth and foliage dynamics of trees both play a significant role in the terrestrial carbon cycle. Yet, crucial knowledge gaps exist in how these two growth components are linked. Our goal is to help bridge these gaps by providing a Northern Hemispheric survey of the connections between, and drivers of, inter-annual wood and canopy-landscape dynamics and phenology. Location Methods Northern (more than 30 degrees N) forest ecosystems. We compared a multispecies network of ca. 700 annually resolved radial tree-growth records with the global inventory modelling and mapping studies-normalized difference vegetation index (GIMMS-NDVI) estimates of foliage greenness between 1982 and 2012. Tree-ring data were assimilated into the simple process-based Vaganov-Shashkin Lite model to derive xylem phenology on a monthly basis and were contrasted against NDVI estimates of canopy phenology. We additionally determined the response of all these vegetation measures to temperature and precipitation. Results
