The International Radiation Symposium 2016 will be held at The University of Auckland, New Zealand and will follow the tradition of previous IRS in providing a forum for the presentation of the best and latest research in Atmospheric Radiation in its many forms. A combination of plenary and parallel sessions will be held Sunday through Thursday, with Friday reserved for a local excursion. There will be an ice breaker on the Saturday evening before the programme starts, and a banquet mid week. Depending on the response, we anticipate about 300 oral presentations as well as several poster sessions.
