Seasonal LAI in slash pine estimated with LANDSAT TM [PDF]

open access: yes
The leaf area index (LAI, total area of leaves per unit area of ground) of most forest canopies varies throughout the year, yet for logistical reasons it is difficult to estimate anything more detailed than a seasonal maximum LAI.
