Abstract A digital sunshine recorder based on the photoelectric principle is described from aspects of the sensor measurement principle and data processing algorithm,which participated in the sunshine duration contrast observational experiments between stations such as Kazuo (Liaoning Province) and Lijiang (Yunnan Province).Through parallel comparison and analysis of digital sunshine recorder,pyrheliometer and dark-tube sunshine recorder,the difference of observation results between several measurement modes was analyzed.The results show that digital sunshine recorder can continuously,automatically and accurately obtain sunshine duration,while dark-tube sunshine recorder has higher measurement results.
