Paper Abstract

In this paper, we develop a method of estimating high temporal-spatial resolution LUE based on the relationship between LUE obtained from Changbai site eddy covariance flux tower and MODIS-derived values of scaled Photochemical Reflectance Index (sPRI). Using MODIS ocean band 11 at 531nm, we tried to detect variations in canopy reflectance related to the xanthophyll cycle. After test MODIS bands 12 and 13 as the reference band because the 570 nm reference band that had been determined to be optimum for calculating PRI in earlier studies is not available on MODIS, strong correlation between MODIS-sPRI and LUE were found only for backscatter reflectance scenes when band 13 (667nm) was used as the reference band with the relationship coefficient is 0.86. Accoring to the method, the retrieved regional LUE can reflect the spatial distribution variation.
