(GSFC-61A0)" Subject: Submission of gscwd31 SINEX series for 4th quarter 2017 SUMMARY OF GSC DORIS SUBMISSION for Oct 1, 2017 to Jan 6, 2018 wd31 SINEX files Date of Report: March 16, 2018 The series gscwd31 is now be our operational series; we will gradually work to extend the time series backwards in time to the start of the Jason-2 mission. The relationship to our previous series (ITRF2014, Lemoine et al., 2016) is as follows: gscwd26: series submitted for ITRF2014 (Lemoine et al., 2016, Adv. Space Re= s.) gscwd27: gscwd26 + SARAL gscwd28: gscwd27 + changes to solar-array orientation modeling described below. gscwd29: gscwd31 replacing DPOD2008_cls_1.15 with DPOD2014_v04. gscwd30: gscwd29 + Jason-3 gscwd31: gscwd29 + Jason-3 with local adjustment for SAA stations on the Jason-3 normal equations. #---------------------------------------------------------- 1.
