Limitations of Satellite-Derived Products for Assessing Actual Photosynthesis in Crops

While satellite-derived products provide valuable information on crop potential photosynthesis, they have limitations in accurately reflecting actual photosynthesis. These products are sensitive to vegetation greenness and canopy structure, which may not always correspond to actual photosynthetic activity. Furthermore, responses of vegetation greenness and canopy structure to changing environmental factors or various stresses are often delayed. In other words, these satellite-derived products can offer insights into crop potential photosynthesis, but may not fully capture the immediate effects of environmental factors or stress on vegetation.
