Long-term Mean Leaf Area Index

Leaf area Index for July

Mean leaf area index for July (calculated over the period 1982-2015).

Global Monthly Mean Leaf Area Index Climatology, 1981-2015

This new dataset provides a global 0.25 degree gridded monthly mean leaf area index (LAI) climatology as averaged over the period from August 1981 to August 2015. The data were derived from the Advanced Very High Resolution Radiometer (AVHRR) Global Inventory Modeling and Mapping Studies (GIMMS) LAI3g version 2, a bi-weekly data product from 1981 to 2015. Long-term global datasets of vegetation LAI are critical to monitoring global vegetation dynamics and for modeling exchanges of energy, mass and momentum between the land surface and planetary boundary layer.
