Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg33 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 eleven sites on the three plates. Hobart-12m and Warkworth are on the Australian Plate, Seshan, Urumqi, Chich10, Aira, Kashima-11, Kunming, Koganei, and Sintotu3 are on the Eurasian Plate, and 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: APSG33 Description APSG Scheduler: NASA Correlator: WASH Start: 2013-140-16:30:00 End: 2013-141-16:30:00 Current yyyyddd: 2013140 (2013.38) ( 16433 MJD, MON. 20MAY.)
