TL;DR: In this paper, the authors present results from analyses of a recently developed satellite-sensed normalized difference vegetation index (NDVI) data set for the period July 1981 to December 1999, showing that about 61% of the total vegetated area between 40°N and 70°N in Eurasia shows a persistent increase in growing season NDVI over a broad contiguous swath of land from central Europe through Siberia to the Aldan plateau, where almost 58% (7.3×106 km2) is forests and woodlands.

TL;DR: There are reported seasonal swings in green leaf area of ≈25% in a majority of the Amazon rainforests, which may be critical to initiation of the transition from dry to wet season, seasonal carbon balance between photosynthesis gains and respiratory losses, and litterfall nutrient cycling in moist tropical forests.

TL;DR: In this paper, the performance of four major global leaf area index (LAI) products at 1/11.2° spatial sampling and a monthly time step was investigated. And the results showed that the CAI values agree better over croplands and grasslands than over forests.

TL;DR: In this paper, the authors describe the main components of this international validation effort, including the current participants, their ground LAI measurements and scaling techniques, and the metadata and infrastructure established to share data.

TL;DR: This paper summarizes the experience of several collaborating investigators on validation of MODIS LAI products and suggests three key factors that influence the accuracy of LAI retrievals that are suggested from the model used to build the look-up tables accompanying the algorithm.
