“…Zenith troposphere parameters were estimated at the start of passes, and only if the previous reset was not within 20 minutes (see Bock et al, 2010, for a more detailed discussion). This solution is as close as possible to the IERS Conventions 2003 (McCarthy andPetit, 2004), and it also includes the most recent improvement in DORIS data analysis, in particular in terms of solar radiation pressure modelling (Gobinddass et al, 2009a(Gobinddass et al, , 2009b as well as in terms of atmospheric drag parameterization (Gobinddass et al, 2010).…”

“…These differences, which are attributed to reference frame realization and from applying different models and/or different model options, highlights the need for an improved GPS observational paradigm in Greenland. Gobinddass et al (2009) provide a non-GPS estimate of the motion of the Thule DORIS beacon, and highlight the importance of addressing systematic errors in geodetic measurements so that accurate surface velocities may be obtained. Most recently, GPS-based studies have identified changing patterns of behaviour in Greenland (Jiang et al 2010;Khan et al 2010), with the authors suggesting that this is due to elastic rebound, severely complicating attempts to measure GIA.…”

Improved Constraints on Models of Glacial Isostatic Adjustment: A Review of the Contribution of Ground-Based Geodetic Observations

et al. 2010

The provision of accurate models of Glacial Isostatic Adjustment (GIA) is presently a priority need in climate studies, largely due to the potential of the Gravity Recovery and Climate Experiment (GRACE) data to be used to determine accurate and continent-wide assessments of ice mass change and hydrology. However, modelled GIA is 123Surv Geophys (2010) 31:465-507 DOI 10.1007/s10712-010-9100-4 uncertain due to insufficient constraints on our knowledge of past glacial changes and to large simplifications in the underlying Earth models. Consequently, we show differences between models that exceed several mm/year in terms of surface displacement for the two major ice sheets: Greenland and Antarctica. Geodetic measurements of surface displacement offer the potential for new constraints to be made on GIA models, especially when they are used to improve structural features of the Earth's interior as to allow for a more realistic reconstruction of the glaciation history. We present the distribution of presently available campaign and continuous geodetic measurements in Greenland and Antarctica and summarise surface velocities published to date, showing substantial disagreement between techniques and GIA models alike. We review the current state-of-the-art in ground-based geodesy (GPS, VLBI, DORIS, SLR) in determining accurate and precise surface velocities. In particular, we focus on known areas of need in GPS observation level models and the terrestrial reference frame in order to advance geodetic observation precision/accuracy toward 0.1 mm/year and therefore further constrain models of GIA and subsequent present-day ice mass change estimates.

“…For example, Zelensky et al (submitted for publication) show that for Jason-2, even with the application of a macromodel, we see geographically coherent 4-5 mm radial RMS shifts between the SLR/DORIS dynamic orbits, and the reduced-dynamic orbits with a period of 118 days. The mismodeling of the radiation pressure can compromise the recovery of geocenter parameters, producing a signature at the draconitic period, at 118 days for TOPEX, and with an annual signal for the sun-synchronous SPOT and Envisat satellites (Gobinddass et al, 2009).…”
