文摘This paper systematically summarizes previous measuring methods and observational instruments for the magnitude of dewfall on land surface,analyzes the characteristics of common observational instruments for land surface dewfall,and describes several ba-sic dewfall measurement methods.Moreover,the basic principles of these methods and instruments are interpreted,and their ad-vantages,disadvantages,and applicability are analyzed.Recommendations for the further improvement of these observational in-struments and the development of dewfall measuring methods are presented,and new technologies and scientific proposals for exploiting dewfall are elucidated.
