Calculating photon flux is based on radiation at ground measured by HyMAP. It is a process of changing the expression of energy. However, this process is not confined to change of measured values. In fact, its significance is helping us to further study how the situation of inside leaf is altered from macro state to micro state. Based on the converted values of photon flux, it is much easier for us explain how leaves absorb and emit photons per second for a type of selected vegetation in a large scale area. On the other hand, it is easier for us to calculate how much energy is absorbed and emitted per unit area, which includes more topics (see the section 55) shown as follows:
1. Effectively estate how much energy is consumed in the process of photosynthesis to produce carbohydrate.
2. How the emitted energy impacts upon the environment?
3. Total values are used for a selected area.
The meaning of the signs shown in Figure 1 to 6 is same as those shown in the last section 47. However, mentioned above, there are many topics involved in explaining many micro processes. It is suggested to read the section 39 and 40.
