摘　　要：日照时数是地面气象观测的基本项目。我国在地面气象观测业务中长期使用暗筒式日照计进行日照时数观测,其自动化程度低,精度较差,资料可比性和一致性难以保证。本文详述了目前国内外各类日照计的测量原理、性能参数,分析了未来能进入业务化运行的日照计的发展趋势。Sunshine duration is a basic item in surface meteorological observation.Jordan sunshine recorder has been long-term used for the observation of sunshine duration in our surface meteorological observation,with disadvantages of low automation,low precision,and being hard to guarantee data comparability and consistency.This paper reviews various measurement principles and performance parameters of domestic and overseas sunshine recorder,and analyses the development tendency of future sunshine recorder used in business application.
