In this study, the parameterization for broadband transmittance in the PAR band is established. On the basis of this parameterization, the scheme is built for estimation of ground PAR under clear-sky condition. At the same time, the sunshine duration is used to be an indicator of cloud, parameterize its influence on the ground PAR, and then estimate the PAR under all-sky condition.
