散射光照度与农业生产、建筑采光等均有密切关系。然而由于没有常规的光气候资料,我国散射照度时空分布状况,至今尚无人研究。 目前,国内外是根据一些日射站进行的照度与太阳辐射同步观测资料,在获得辐射光当量的基础 相似文献

From 1983 to 1984,14 solar radiation observation stations which are located in different climate zoneswere chosen for the simultaneous observation of natural illumination with the hourly observation of insola-tion every day.In this paper,according to the data the light equivalent of total solar radiation (LEOTSR)has been given.A multivariate regression equation is employed to calculate the annual and monthly meanvalues of the LEOTSR at 14 observation stations.The variables of the equation include latitude,elevation,surface mean absolute humidity and sunshine duration.The results show that the relative errors are lessthan 10%.The LEOTSR for 464 observation stations was calculated by means of the multivariate regression equationswhich were obtained by the data of 14 observation stations.The total illumination is given by the LEOTSRmultiplying the total radiation.The climatological values of total illumination for each station are alsocalculated according to its LEOTSR and solar radiation.Finally,the climatological charts of total illuminationin China have been drawn. 相似文献

本文根据1983—1984年全国14个不同气候特点的日射站每日逐时照度与日射同步观测资料计算了总辐射光当量值,提出用纬度、海拔高度、地面平均绝对湿度和日照时数建立计算总辐射光当量的多元回归方程。用14个测站全年和各月平均总辐射光当量值检验所建立多元回归方程计算的相应总辐射光当量值表明,计算值的相对误差均小于10%。 我们用14个测站资料建立的计算总辐射光当量回归方程计算了全国464个测站的总辐射光当量值。总照度可由总辐射光当量与总辐射的乘积获得。根据各测站的总辐射光当量和总辐射值,便可计算出这些测站的光气候值,绘制我国光气候图。 相似文献
