International Joint Laboratory of Regional Pollution Control (IJRC) convened the 2022 annual meeting online on 14th, October. Prof. Andreas Wahner, IJRC Dean of German counterpart, Dr. Anna Novelli, Dr. Thorsten Hohaus, Dr. Franz Rohrer, Dr. Hendric Fuchs and Dr. Seren Zorn from Jülich Research Center and IJRC Dean of CESE-PKU, Prof. Yuanhang ZHANG, Academician of Chinese Academy of Engineering, Prof. Min HU, IJRC Executive Dean, Prof. Limin ZENG, Dr. Keding LU, Dr. Song GUO, Dr. Xin LI, Dr. Zhijun WU from CESE-PKU, and visiting scholar Dr. Zhaofeng TAN attended the meeting, which was chaired by Prof. Andreas Wahner.

First of all, both parties reported current and future research projects respectively. Dr. Anna Novelli reported her research progress in mechanism of degradation of AVOC/BVOC, and in instrument development in OH-measurements. Dr. Thorsten Hohaus shared his current research focus on aerosol chemistry, mainly on SVOC, HOM and nighttime chemistry. Prof. Min HU gave a lecture titled “Summarize 2022 and look forward to 2023”, in which she first gave a general summary on summer school and joint publications in these years, then she focused on current major researches undertaken in four aspects, i.e. technique development, atmospheric oxidation research, atmospheric aerosol research and air quality and climate change. Dr. Keding LU, Dr. Xin LI, Dr. Song GUO, and Dr. Zhaofeng TAN shared their research project and research work as well. Prof. Min HU ended her report with her sincere wish for IJRC, that is “mutual help, win-win, mutual success”.

After presentation, a heated discussion was followed on what to done next. Prof. Andreas Wahner suggested setting small groups could be helpful to identify real common interests based on current research projects of both sides and an outlined of what could be done in next 2-3 years should be made. Prof. Yuanhang Zhang echoed Prof. Wahner’s suggestion, with the hope that both sides could undertake more efficient collaborative research by clarifying detailed research interests from general research subjects. Finally, a brief arrangement was made of what to be done in the near future.
