Abstract Based on the sunshine duration observed by using DFC 2 photoelectric digital sunshine recorder and dark-tube sunshine recorder from 3 national stations in Rizhao city from January to June of 2019,and by use of the statistical methods such as difference value,relative difference value and linear trend,etc,this paper makes a comparative analysis of the sunshine duration difference between the photoelectric digital sunshine recorder and dark-tube sunshine recorder,which observed on a monthly,daily and hourly basis respectively and under different meteorological conditions.It is concluded that the sunshine duration given by photoelectric digital sunshine recorder is slightly less than that by dark-tube sunshine recorder and relatively better consistency of data can be obtained by the two.The photoelectric digital sunshine recorder,by virtue of its advantages such as high resolution,high sensitivity to light and being less affected by human factors,can be used to reflect the variations of sunshine more objectively during sunrise and sunset periods.The research results can provide a reference for the operation,maintenance,data statistics and relevant applied researches of photoelectric digital sunshine recorder.
