太阳辐照度下降的有效黑子模式和太阳辐照度可变性的有效光球活动区模式

本文作者提出了描述太阳辐照度下降的新模式--有效黑子模式;对1980年4月1日至7月16日的北京天文台黑子照片进行了保守测量;就有效黑子模式计算出的太阳辐照度与同一时期"太阳峰年使者"卫星观测到的太阳总辐照度进行了比较,两者在数值上非常接近,并且呈甚佳线性相关;进而提出了描述太阳辐照度可变性的新模式--有效光球活动区模式;从而在上述基础上提出了今后应继续的工作。 

REDUCTION OF SOLAR IRRADIANCE BY THE PRESENCE OF EFFECTIVE SUNSPOTS AND VARIABILITY OF SOLAR IRRADIANCE BY THE PRESENCE OF EFFECTIVE PHOTOSPHERIC ACTIVE FEATURES

This paper presents a new idea by modelling the reduction of solar irradiance by the presence of effective sunspots.Based on the author's personal conservative measurement of the sunspot pictures of April 1 through July 16,1980,a comparison between the theoretical solar irradiance and the total solar irradiance measured by SMMspacecraft has been made,which shows a reasonably good agreement and high correlation (r=0.78).Moreover,the author presents further an improved model of solar irradiance variability by the presence of effective active features on the photospherie disk,which is as follows.here Au,Apu,Af and A,denote the areas of umbrae,penumbrae,faculae and the visible solar disk,respectively;θu,θpu,θf are the umbral,penumbral and facular contrast values;θfh represents the limb darkening that depends on the helioeentric-angle θ.The author also sets forth several problems that need further investigations.
