The first meeting took place in 1984 to commemorate Prof. Sidney Benson’s 65th birthday. The meeting participants enjoyed discussions and exchanges on the topic of kinetics relevant to chemical processes driven by photons in the atmosphere. It was then proposed that such a meeting should be held each year in the Southern California atmospheric chemistry community. The resulting symposium got a name “Informal Symposium on Kinetics and Photochemical Processes in the Atmosphere (ISKPPA)”. Over the years, the topics discussed at the symposium went beyond kinetics and photochemistry of atmospheric processes, and started to include aerosol science, air quality, climate sciences, etc. Therefore, the meeting got renamed into “Informal Gathering on Atmospheric Science and Photochemistry (IGASP) starting in 2022.

Previous Meeting Information

Please check the list of invited speakers from the most recent symposia. We have been able to locate programs for some of the symposia but there are many gaps. If you have older programs please e-mail them to Sergey Nizkorodov. Note that 2020 was skipped because of the Covid-19 lockdown. Also, because of Covid perturbations the symposium timing shifted in from spring to fall.
