A PAR model is utilized to estimate daily PAR from routine meteorological parameters at CMA stations. The estimate is evaluated against measurements at ten Chinese Ecosystem Research Network (CERN) stations. Comparison with a locally-calibrated model indicates that the estimate has a comparable or even higher accuracy than the local model calibrated. Finally, a 50-year dataset of daily PAR at 716 CMA stations over China is reconstructed by the validated model, and its climatology and long-term variations over China are analyzed.
