If there are others who should be included in this category, please notify B. Huebert.

The group began by selecting Barry Huebert to serve as Lead Scientist for ACE-Asia. It then named an Executive Committee, which will serve to make judgements and provide comments on issues for which a rapid response or a smaller group discussion is appropriate. The ExCom membership is:

Barry Huebert
Young-Joon Kim
Kimitaka Kawamura
Mingxing Wang
Tim Bates
John Gras
Tom Choularton
John Seinfeld (Karsten Suhre was the other possibility)

If a commitment to ACE-Asia is made by China-Taipei, they would also be encouraged to include a representative on the SSC and the ExCom.

The SSC then discussed the role of the IGAC FAA Activities and APARE in managing the four components of ACE-Asia. There seemed to be agreement that ACI would manage the Cloud- Aerosol component; ACAPS and MAGE would manage the Survey and Evolution component; and APARE would consider managing the Network and Time-Series Observations component. The Direct Radiative Effect component, however, is somewhat less certain at the moment due to the changes in DARF and SUTA during the reorganization of IGAC. It is hoped that this can be resolved in the next several months, since direct radiative forcing and satellite validation are such important parts of ACE-Asia.

We also discussed the need to produce focused Science and Implementation Plans for each of the components, rather than a single one for all of ACE-Asia. The experiment as a whole is simply too broad, and we have been criticized for trying to do too much at once. The four S&IP's will each be much more focused on goals that can be achieved within the context of either a campaign or the network time-series observations. Discussions in the SSC and the Science Team meetings clarified that the components would be organized along lines of logical sets of observations (the three potential campaigns vs time-series), rather than characterization activities vs process studies.

The SSC adjourned in preparation for the subsequent Science Team meeting.
