The rationale is to reach out to the solar physics community in Asia, where there has been ever growing interest and use of data from the Interface Region Imaging Spectrograph (IRIS) mission. The workshop is designed for researchers and students in this region. The program will be similar to that of the IRIS-5 workshop in India and will consist of mainly tutorials on UV spectroscopy, IRIS data analysis, radiative transfer, and IRIS-related quiet Sun and flare simulations. There will be lectures as well as hands-on sessions. A secondary goal of the workshop is to facilitate future IRIS-coordination and synergy with ground-based instruments (such as NST, NVST and ONSET) built/operated by solar physicists in this region.
