This study provides empirical relationships between photosynthetically active radiation (PAR) and broadband clear‑sky indices at ground level for both the PAR global irradiance and its direct component. Once multiplied by the irradiance in clear‑sky conditions, the clear‑sky index provides the irradiance under cloudy conditions. The relationships are developed by the means of radiative transfer simulations of various realistic atmospheric states including both ice and water cloud phases. For the direct component, the PAR clear‑sky index is equal to the broadband clear‑sky index. For global irradiance, several linear relationships are proposed depending on the availability of cloud properties namely cloud phase and cloud optical depth. The developed relationships are validated numerically and experimentally by using ground-based measurements from the SURFRAD network in the U.S.A. Overall, it has been found, a squared correlation coefficient R 2 $R^{2}$ close to 1.00 and a relative bias (relative root mean square error) in absolute value less than 3 % (6 %) with respect to the means of the relevant measurements, demonstrating a high level of accuracy of the proposed relationships.
本研究提供了光合有效辐射（PAR）与地面宽带晴空指数之间的经验关系，包括 PAR 全球辐照度及其直接分量。晴空指数乘以晴空条件下的辐照度，就得到了多云条件下的辐照度。这些关系是通过对包括冰云和水云阶段在内的各种现实大气状态进行辐射传递模拟而建立的。对于直接分量，PAR 晴空指数等于宽带晴空指数。对于全球辐照度，根据可用的云属性（即云相和云光学深度），提出了几种线性关系。利用美国 SURFRAD 网络的地面测量数据，对所建立的关系进行了数值和实验验证。总体而言，发现平方相关系数 R 2 $R^{2}$ 接近 1.00，相对于相关测量的平均值，相对偏差（相对均方根误差）的绝对值小于 3 %（6 %），表明所提出的关系具有很高的准确性。
