Summary:

The RSS-04 team collected several data sets related to leaf, plant, and stand physical, optical, and chemical properties. This data set contains leaf area indices and FPAR measurements which were taken at the three conifer sites in the BOREAS SSA during August 1993 and at the jack pine tower flux and a subset of auxiliary sites during July and August 1994. The measurements were made with LAI-2000 and Ceptometer instruments. The measurements were taken for the purpose of model parameterization and to test empirical relationships that were hypothesized between biophysical parameters and remotely sensed data.

A guide document which includes more information about this data set can be found at https://daac.ornl.gov/data/boreas/RSS/r04laifd/comp/RSS04_LAI_FPAR.txt.

ORNL DAAC maintains information on the entire BOREAS Project.
