Validation of MODIS LAI Product Over Temperate Forest

초록

MODIS LAI has been one of key products for analyzing the quantitative aspects of terrestrial ecology. This study was designed to validate MODIS LAI product by using the reference LAI map that was derived from both ground measurements and ETM+ surface reflectance. The study area, the Kwangneung Experiment Forest in Korea, covers mixed species of deciduous and conifers of temperate forest. Throughout the growing season of 2002, we have measured LAI at the 30 sample plots using an optical device. Ground measured LAI data were then correlated to the ETM+ reflectance to produce a continuous map of LAI over the study area. Preliminary comparison between MODIS LAI and the reference LAI map showed the lower LAI values from the MODIS product
