Chi Epsilon Pi (ΧΕΠ) (Also known as XEP) is a national honor society for outstanding students in the field of meteorology/atmospheric sciences. The purpose of the society is mainly twofold: to serve as a means for awarding distinction to students who have high scholastic ability and promise of achievement in meteorology; and to promote student interest in advanced study of meteorology and related sciences. The society is now known to have a well-defined national organizational structure. The chapters exist at various institutions, which usually have a notable meteorology program; however, the existence of a chapter is not known to be defined by common criteria.
The first official chapter of Chi Epsilon Pi was founded at the University of California, Los Angeles in 1951. From there it developed into a national organization.
