Dear colleagues in IUFRO Division 8, I hope you are doing well. As for the captioned matter, the postponed 10th International Conference on Acid Deposition, ACID RAIN 2020, will be held in April 2023. I am pleased to inform you that the conference organizer has decided to extend the due date of the abstract submission for one month: Until 31 October, Monday, 2022 https://www.acidrain2020.org As you may know, the Government of Japan has decided to allow visa-free individual tourists from 11 October 2022. So, the ordinary daily life is recovering gradually. I hope you can enjoy holidays in Japan before/after the conference. I would appreciate it if you (re)consider the possibility of participating the conference in April 2023. Also, please share the information in your communities. I am looking forward to seeing many of you in Niigata in April 2023.
