Sun-induced leaf fluorescence was inferred by using high resolution (0.5 cm(-1)) radiance measurements and simulated spectra of the solar irradiance at the ground level, in the region of the O(2)-B absorption band. The minimization of a cost function was performed in the Fourier transform domain in order to make an accurate fit of the Instrumental Line- Shape that convoluted the simulated spectrum. Second- order polynomials were used to fit the leaf fluorescence and reflectance in the 100-cm(-1)-wide spectral window. The scale and the instrumental conversion factor were also fitted in order to obtain an accuracy that could not be attained by using the radiance measurements alone.
通过使用高分辨率（0.5厘米⁻¹）辐射测量以及地面太阳辐照度在O(2)-B吸收带区域的模拟光谱，推断出太阳诱导的叶片荧光。在傅里叶变换域中对代价函数进行最小化，以便准确拟合卷积模拟光谱的仪器线形。使用二阶多项式在100厘米⁻¹宽的光谱窗口中拟合叶片荧光和反射率。还对比例和仪器转换因子进行了拟合，以获得仅使用辐射测量无法达到的精度。
