%X This paper presents an in-depth analysis on the influence of mesophyll structure parameter N in PROSPECT model on leaf reflectance and transmittance spectra. Optimal N values of samples in LOPEX93 data set are calculated by minimizing a whole-band cost function using the iterative method. Simulated spectra under calculated optimal N values are compared with measured ones. Further,inversions of chlorophyll and water content under different N values are performed. Results show that: (1) the influence of N involves the whole-band spectra from visible to near infrared,and the influence decreases with its values; (2) simulated spectra with optimal N ,which is calculated by minimizing a whole-band cost function using the iterative method,match very well with measured spectra; (3) the inversion accuracy of chlorophyll and water content by using overestimated N is better than that by using underestimated N ; (4) the inversion accuracy of water content is significantly better than that of chlorophyll partially due to the selection of cost function.
