21. Intra-Initiative Learning Development of greater interdisciplinarity among the participants in the WCIAS This development is an ongoing process Catalyzes integration within NCAR

22. Initiative Management and Planning

23. Four meetings with interested NCAR staff and several ESIG- specific planning meetings held to develop the three themes (second half of 2000 and first half of 2001) Consultation with external collaborators Written contributions from core group of interested staff, including all ESIG scientists Several document iterations One follow-up planning meeting held August 2001 Several more detailed follow-up planning meetings on individual themes held in September/October 2001 Initial funding provided in FY 2002 ($214K) General Planning Process of Assessment Initiative
