Research Abstract

In this study, the amount of carbon absorption by terrestrial vegetation that uses the satellite data is made highly accurate by using the spectrum reflectance and the carbon flux data observed on the ground, and the satellite data. As a result, PRI (Photochemical Reflectance Index) can be calculated by using the MODIS (Moderate Resolution Imaging Spectroradiometer) data. It is possible to estimate the net primary production in high accuracy using LUE (Light Use Efficiency) calculated by the this index that uses the satellite data.
