Many individuals in attendance volunteered to work within a group to help tackle the problems associated with estimating of LAI and FPAR from remote sensing.
Although some in attendance volunteered to participate, others of you were nominated by your peers for your expertise.

Ground truth will consist of TRAC and LAI-2000 measurements of LAI and FPAR taken along transects within the BOREAS tower sites by Jing Chen, LAI and FPAR estimations made from hemispherical photography taken by Paul Rich, allometric measurements taken by Tom Gower's group, and moss spectral measurements by John Miller and Jing Chen.
What we plan to do is to provide a dataset of georeferenced ASAS (nadir), CASI, and helicopter MMR and SE590 data extractions coincident with ground measurements. Two transects are to be used: one runs from the tower SE for 300 m (used in 1994) and one to be established this summer will go from the tower due west for 500 m.
What we need from each of the modelers is a list of the inputs you will need for development and testing of your models. With the summer field effort quickly approaching we would like to identify any data gaps ASAP. Please send additional data needs and modifications to measurement design for the SSA-OBS by the end of next week (June 21st).
Known Data Needs
Once this site-level data set is complete, each participating scientist would run their algorithm on the data for quantitative evaluation, and in addition, produce a bio parameter map of the SSA-OBS WAB for use by other investigations. We expect to use several approaches including the traditional method using VIs, spectral unmixing for shadow fractions, and geometric-optical model inversion. Models to be used for this purpose include the 3-D model (Myneni), GeoSail (Huemmrich), GORT/SNTHRM (Li and Strahler, and Davis), and 4Scale (Chen). The synergetic use of SAR and optical data will also be explored (Saatchi and Chen).
We would anticipate this occurring reasonably soon after the summer IFC, with results to be reported at the next science workshop in Dec. '96 or Jan '97.
There will be an initial meeting of interested individuals after the first BOG conference at the commencement of IFC-2, on July 8th, at SSA OPS (Snowdrifters).
We look forward to hearing from you,
Please send responses to Jaime Nickeson
