Topic: UHECR Observational Results and Next Generation Projects
Lecturer: M. Teshima

In this lecture, the observational results on Ultra High Energy Cosmic Rays (UHECRs) are discussed. Especially the energy spectrum and the arrival direction distribution of UHECRs are important measures to understand the origin of UHECRs. The energy determination methods and their systematic errors in ground arrays and air fluorescence detector techniques will be discussed in detail.

New generation projects Auger, Telescope Array and EUSO will be also discussed.
