1. SNARF Chair's Report Geoff Blewitt Recap of prior meetings SNARF status Funding status

2. Recap of Prior Meetings 1) 2004-01, UNAVCO Inc., Boulder, CO. - Initial meeting. Establish key areas of research. 2) 2004-05, Joint Assembly, Montreal, Canada. - Special AGU session followed by workshop. Exploration state of the art. 3) 2005-03, EarthScope National Meeting, Santa Ana, NM. - Workshop followed by plenary presentation. - Foundation for initial SNARF realization. Stochastic approach to GIA. 4) 2005-06, UNAVCO/IRIS Meeting, Stevenson, WA. - Education of users. SNARF 0.0 presented. 5) 2006-03, UNAVCO Science Meeting., Denver, CO. - SNARF 1.0 and PBO. Operational analysis for future SNARF realizations. 6) 2006-11, Natural Resources Canada, Ottawa, Canada. - Explore current weaknesses in frames, and ways to improve SNARF 7) 2007-03, EarthScope National Meeting, Monterey, CA. - User's experiences and needs, and planning future development.

3. SNARF Status SNARF 1.0 operational in PBO analysis SNARF 1.n... from additional data and possibly additional data analysis groups SNARF 2.0 awaits IGS reanalysis in ITRF2005 using new antenna models (station + satellite) Progress on “standard” and accurate GIA models expected to be slow and so current stochastic approach will continue for now Moving toward increasing reliance on NGS and NRCan for maintenance of SNARF

4. Funding Status Grant 1: ~$40K Jan 2004- Jan 2006  + 1 yr no-fee extension, which expired Jan 2007. Grant 2: ~$40K Jan 2006 – Dec 2006  Apparently a clerical error (should be 2 yr)  Change in expiration date granted (to Dec 2007) Funding issues  Funds underspent (Grant 1 carry-over,...)  More than sufficient funds for 2007  Suggest special session + workshop at Fall AGU  Follow on grant unlikely, but no-cost extension through 2008 is possible
