Fourteen GLS-2000 Landsat scenes acquired from different dates are normalized to the
MODIS-like surface reflectance by using MODIS Nadir BRDF-adjusted reflectance (September
21-October 6, 2000) as a reference. The normalized surface reflectance (

) reduced the seasonal
variations in the original surface reflectance mosaic (

Similar normalization approach can be applied for retrieving biophysical
parameters. In Fig.

, MODIS Leaf Area Index (LAI) 8-day composite product
(MOD15A2, Myneni et al.
2002
) from June 2-9, 2002, was used as a reference to
retrieve LAI from Landsat data (WRS-2 path 26 and row 31). The LAI from
