Willis (Ed.), JOURNAL OF GEODESY 80(8-11):609-624, DOI: 10.1007/s00190-006-0090-4 Last changes in the time series data analysis: From 2009/01/04 for wd24 (lca09004wd24.snx) and 2008/12/28 for wd26 (lca08363wd26.snx) to 2010/01/02 (lca09361wd24.snx, lca09361wd26.snx) ------------------------------------------------------------------------ ----------------------------------------------------------------- Same data processing (see lcawd24.snx.dsc) but: -no atmospheric loading correction applied in the data processing (so, no post-processing to remove the atmospheric loading correction) The new series wd26 just includes Jason-2 in addition. From 2010/01/03 (sinex from lca10003wd24.snx and lca10003wd26.snx) ------------------------------------------------------------------ Same data processing but: - no atmospheric loading correction applied in the data processing - drift terms of EIGEN-GL04S_ANNUAL not considered except for C20, C30, C40, C21, S21 (IERS standard values applied) From 2011/04/01 (sinex from lca10276wd24.snx and lca10276wd26.snx) ------------------------------------------------------------------ A new version of GINS is used (10.3d1) including: - improved attitude models for Topex, Jason-1, Jason-2, Envisat - correction on frequency bias ajustment These improvements impact in particular the orbits and the vertical station positions wd24 = SPOTs + Envisat wd26 = SPOTs + Envisat + Jason2 wd28 = SPOTs + Envisat + Jason2 + Cryosat2 Please do not reply directly to this message, but send comments and suggestions to IDS.central.bureau@cls.fr
