摘要:
2005年8月对贝加尔湖地区的太阳分光辐射(总辐射Q、紫外辐射UV、可见光辐射VIS、近红外辐射NIR)、光合有效辐射PAR、气象参数等做了短期测量,初步得到了Q、UV、VIS、NIR、PAR等的变化特征。观测表明,小时累计值之比UV/Q、VIS/Q、NIR/Q、PAR/Q、PAR/VIS等相对稳定,并表现出明显的日变化和逐日变化,它们的平均值分别为0.054、0.435、0.513、2.118、4.874。基于对测量数据的分析,利用辐射和气象台站常规的测量数据,建立了计算实际天气PAR、VIS小时值的经验公式以及PAR与VIS转换关系式,计算值与观测值符合得较好。PAR、VIS计算值与观测值的相对偏差小于4.5%。考虑到辐射资料的可用性,建立了使用不同参数情形下的经验公式,并讨论了有关参数的使用。

Abstract: Integrated observations were made of solar radiation (including global radiation (Q), UV, visible radiation (VIS), near infrared radiation (NIR)), photosynthetically active radiation (PAR), and me-teorological parameters at Baikal Lake in August 2005. The characteristics of Q, UV, VIS, NIR, PAR were obtained. The results show that the ratios of hourly sum UV/Q, VIS/Q, NIR/Q, PAR/Q, PAR/ VIS were relatively stable and displayed evident diurnal and daily variations. Their averages were 0.054, 0.435, 0.513, 2.118 and 4.874, respectively. Based on analyzing observational data and uti-lizing routine observational data at solar radiation and meteorological stations, the empirical formulas for calculating hourly sums of PAR and VIS, and relationship between PAR and VIS were developed under all sky conditions. The calculated PAR and VIS were in good agreement with measured, and their relative biases were less than 4.5%. Considering the availability of different solar radiation data, the empirical formulas using different parameters were developed, and the option of selecting different parameters was also discussed.
