Relationship between Light Use Efficiency and Photochemical Reflectance Index using MODIS Data in Japan

Recent research has shown that the photochemical reflectance index (PRI) can be related to LUE with some success. However, these researches did not use satellite data to calculate PRI.

Summary:Recent research has shown that the photochemical reflectance index (PRI) can be related to LUE with some success. However, these researches did not use satellite data to calculate PRI. In this study, we used not only laboratory and field data, but also the Moderate Resolution Imaging Spectroradiometer (MODIS) data to calculate PRI and investigated the usefulness or effectiveness of PRI from MODIS data. At the leaf level, PRIMODIS was linearly related to the original PRI. At the canopy level, the relation between PRI and PRIMODIS was different depending on the condition of the plant and the correlation between PRIMODIS and PAR showed a difference from that of PRI and PAR. At the satellite level, the correlation between PRIMODIS and solar radiation showed a difference from previous research. These results provide a guide for the use of PRI from satellite data as an index of LUE.
