****************************************************************************** dorisreport 31-Dec-2012 23:23:24 Message No 3200 ****************************************************************************** Author: "Lemoine, Frank G. (GSFC-6980)" Subject: Submission of GSC wd15 series for 2012 (2012-doy001 to 2012-doy274) SUMMARY OF GSC DORIS SUBMISSION December 31, 2012 NB. 5 satellites (SPOT4, SPOT5, ENVISAT, CRYOSAT2, JASON2) are included from 2012-doy001 through the week of 2012-doy085. From the week of 2012-doy092, only 4 satellites contribute to this series: (SPOT4, SPOT5, CRYOSAT2, JASON2) SPECIAL NOTE: 12/31/2012. We make a new series delivery, wd15, that supercedes the previous delivery, wd13. The wd13 series will no longer be updated. It is intended that wd15 will be the progenitor of the GSC DORIS submission to the IDS combination for the next ITRF, pending investigation of other improvements that we wish to implement. With respect to the wd13-series, we make the following changes and updates: I. Correct an input error to GEODYN that appears to have affected the tide model computations for some of the SPOT satellites. II. Replaced the "fit" coefficients for C20, using a 18.6yr fit rather than a 9.3 yr fit to the 1993-2012 SLR/DORIS 4x4 time-variable gravity time series. III. Apply the ocean pole tide. IV. Systematically estimate 2hr Cd's (Drag coefficients) with a time correlation of 2hrs and exponential decay from t=t0 for SPOT4, SPOT5, ENVISAT & Cryosat2 (The lower altitude DORIS satellites). (Previously some satellites had 4hr time periods for cd estimation). Also the mean (a priori) value of drag is applied per satellite (calculated by year (2004-2012) or by quarter (2010-2011), - as suggested by the results of the previous series (wd13). There was no change in Jason-2 cd estimation strategy which remains cd-per 8 hrs. V. Apply updates to SLR modelling and bias estimation for 2010 - 2012 (this does not affect the DORIS SINEX below per se, but comes into play regarding some of the SLR/DORIS vs DORIS-only orbit comparisons). For the period of this submission (2012), we notice no significant difference in the Helmert Parameters (Tx, Ty, Tz, scale) and WRMS between wd13 and wd15. ----------------------------------------------------- 1.
