Two team meetings for the members will be held to review progress and present new results, and to facilitate intensive discussion.

• Initial discussions on collaboration plans will take place during the 9th international workshop on long-term changes and trends in the atmosphere, to be held September 19-23, 2016 (Germany) where most team members will attend.
  
  
•  ISSI Bern meeting, tentative May 1-5, 2017. We will review prior results in members’ expertise areas. We will discuss possible clues that may help answer those challenging questions. We will discuss contributions individual members will have to make for the next meeting and for the success of the project.
  
  
• ISSI Beijing meeting, tentative May 2018. This meeting will take place prior to the biannual international workshop on long-term changes and trends in the atmosphere (expected to be held June-September, 2018). In this team meeting, we will  address the scientific questions proposed and identified in the previous meeting.  For this Beijing meeting, we plan to invite 2-3 self-supported scientists (mostly from China) to participate our activities.
  
  
• Between these planned meetings, the team members will work on their assignments and  keep in touch via email and teleconf. Some of the members will meet during other professional meetings for further discussion and communication.
