Welcome to the Land Product Validation 1st LAI Meeting Page




	First Workshop - LAI Intercomparison June 7-8, 2001 ESA, Frascati, Italy

The initial step for this activity was a workshop held in June, 2001. This provided an opportunity to share insights and evaluate progress on LAI product validation and place this work in the context of the Global Observation of Forest Cover (GOFC) program. See list of attendees.
