****************************************************************************** dorisreport 06-Sep-2013 22:07:02 Message No 3426 ****************************************************************************** Author: "Lemoine, Frank G. (GSFC-6980)" Subject: Delivery of gscwd18 SINEX files (2013/097 to 2013/181) SUMMARY OF GSC DORIS SUBMISSION for 2013 wd18 SINEX files September 6, 2013 SPECIAL NOTE from 05/31/2013. We are making a new series delivery, wd18. With respect to the previous wd15 series, we made the following changes and updates: I. Used a new version of GEODYN which included a change to the calculation of the Doris frequency beacon correction. II. Changed the Envisat, Spot 2, and Spot 3 macromodels. Note that the SPOT-4 spacecraft was decommissioned, so the last week it contributes to the weekly solutions is 130609. #---------------------------------------------------------- 1. List of files submitted for 2013 SINEX files in Normal equation format. All files have 7 X and 7 Y EOP weekly parameters. wd18 series ( Spot4, Spot5, Jason 2, Cryosat 2) NAME DATE No. of No. of Stations Coord parms Used Edited gsc13097wd18.snx 130407 129 43 2 gsc13104wd18.snx 130414 129 43 3 gsc13111wd18.snx 130421 135 45 1 gsc13118wd18.snx 130428 129 43 4 gsc13125wd18.snx 130505 129 43 4 gsc13132wd18.snx 130512 126 42 1 gsc13139wd18.snx 130519 132 44 1 gsc13146wd18.snx 130526 135 45 1 gsc13153wd18.snx 130602 129 43 3 gsc13160wd18.snx 130609 135 45 1 gsc13167wd18.snx 130616 150 50 1 gsc13174wd18.snx 130623 150 50 1 gsc13181wd18.snx 130630 144 48 2 2.
