摘要

Photosynthetically active radiation (PAR) is an essential parameter in vegetation growth models and soil carbon sequestration models. A method has been developed by which instantaneous PAR can be calculated with high accuracy from Moderate Resolution Imaging Spectroradiometer (MODIS) atmosphere and land products. This method is based on a simplification of the general radiative transfer equation, which considers five major processes of attenuation of solar radiation: 1) Rayleigh scattering, 2) absorption by ozone and water vapor, 3) aerosol scattering, 4) multiple reflectance between surface and atmosphere, and 5) three terrain factors: slope and aspect, isotropic sky view factor, and additional radiation by neighboring reflectance. A comparison from 2006 of 108 retrieved results to filed measured PAR, and the R² of 0.855, in the Yucheng site of the Chinese Ecosystem Research Network (CERN) indicates that the computed results can adequately interpret actual PAR.
