We propose a new filtering procedure for post-processing GRACE-based monthly gravity field solutions provided in the form of spherical harmonic coefficients. The procedure is tuned for the optimal estimation of linear trends and other signal components that show a systematic behavior over long time intervals. The key element of the developed methodology is the statistically optimal Wiener-type filter which makes use of the full covariance matrices of noise and signal. The developed methodology is applied to determine the mass balance of the Greenland ice sheet, both per drainage system and integrated, as well as the mass balance of the ice caps on the islands surrounding Greenland. The estimations are performed for three 2-year time intervals (2003–2004, 2005–2006, and 2007–2008), as well as for the 6-year time interval (2003–2008). The study confirms a significant difference in the behavior of the drainage systems over time. The average 6-year rate of mass loss in Greenland is estimated as 165 + 15 Gt/year. The rate of mass loss of the ice caps on Ellesmere Island (together with Devon Island), Baffin Island, Iceland, and Svalbard is found to be 22 + 4, 21 + 6, 17 + 9, and 6 + 2 Gt/year, respectively. All these estimates are corrected for the effect of glacial isostatic adjustment.

[Termes IGN] variation temporelleRésumé : (Auteur) In this paper, we present the results of an experiment aiming to compare measurements of atmospheric delay by synthetic aperture radar (SAR) interferometry and GPS techniques to estimates by numerical weather prediction. Maps of the differential atmospheric delay are generated by processing a set of interferometric SAR images acquired by the ENVISAT-ASAR mission over the Lisbon region from April to November 2009. GPS measurements of the wet zenith delay are carried out over the same area, covering the time interval between the first and the last SAR acquisition. The Weather Research and Forecasting (WRF) model is used to model the atmospheric delay over the study area at about the same time of SAR acquisitions. The analysis of results gives hints to devise mitigation approaches of atmospheric artifacts in SAR interferometry applications.

[Termes IGN] signal GalileoRésumé : (Auteur) Reflectometry systems analyze reflected GNSS signals to investigate properties of the reflecting surface and to derive various parameters from that surface. The emergence of additional GNSS systems has increased the availability of multiple signals on multiple frequencies, which provides the opportunity for developing new techniques for applying reflectometry. This article describes an E1/E5a/E5b ground-based altimetry application that has been tested with Galileo signals. The innovative aspect of this system resolves carrier phase ambiguities as in RTK positioning to achieve millimeter accurate surface height measurements, including the use of Galileo AltBOC code measurements for instantaneous decimeter accurate height values. New applications enabled by this technique may include monitoring of large buildings, landslides, or precision passive radar.
