| Outline of Final Research Achievements |
The algorithm of estimating gross primary production of vegetation using satellite sensor data was developed. The main characteristics of the algorithm are using the light response curve of photosynthesis in the algorithm, and dividing two parts as photosynthesis capacity, which is in the condition plants photosynthesizes with less stress, and it’s suppression. The parameters of a light-response curve were determined using the estimation formula. The formulas were divided into three groups as grass and open shrubs, woody plants except for a tropical rain forest. The suppression part was studied focusing on stomata opening and closing using thermal imagers for leaf and canopy level. The estimation accuracy of the diurnal variation pattern of the leaf and canopy conductance was better than the absolute value.
