摘要
对无气象站或有站而不观测太阳净辐射(Rn)的地区提出利用太阳常数、地理纬度、太阳赤纬角、太阳时角、实际日照时间、最大可能日照时间计算太阳净辐射(Rn)及ET0的方法,并对该方法的可行性进行了分析,并指出计算过程中应注意的关键环节。
For some area where there are not meteorological station, or there are meteorological station but some weather variables are missing, this paper provides a method for estimating ET0 by using the solar constant, latitude, sunset hour angle, solar declination, actual and maximum possible duration of sunshine and analyzes the reliability of the method. The key procedures of this method are also discussed.
