Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg34 Prepared by C. Thomas, NVI, Inc./GSFC =========================================================== The primary purpose of this Asian Pacific Space Geodynamics (APSG) session is to continue monitoring the relative motions of the plates in the Asia-Pacific region. This session involves thirteen sites on five plates. Aira, Kunming, and Seshan are on the Eurasian plate. Chich10 is on the Philippine Sea plate. Hobart-12m, Katherine, Warkworth, and Yarragadee are on the Australian plate. Kashima-34m, Kashima-11m, Koganei, and Tsukuba are on the North America plate. Kokee is on the Pacific plate. Thus, this session will produce critical data for the investigation of the current crustal motions in the Asia-Pacific region combined with the data from the APSG SLR and GPS campaigns. Also, this experiment will improve the accuracy of the geocentric coordinates of the participating stations. =========================================================== ----- Parameter listing -------------------------------------- Experiment: APSG34 Description APSG Scheduler: NASA Correlator: WASH Start: 2014-252-17:30:00 End: 2014-253-17:30:00 Current yyyyddd: 2014252 (2014.69) ( 16910 MJD, TUES 9SEP.)
