Aconcagua peak geodynamics from GPS observations, Mendoza, Argentina: preliminary results
Aconcagua peak geodynamics GPS Argentina
2010/1/28
In 2005, the SIGMA Program (Mount Aconcagua GNSS Research System) was implemented to investigate the geodynamics of the Aconcagua mountain region in the Central Andes. For this purpose, a continuously...
GPS detection of ionospheric perturbation before the 13 February 2001,El Salvador earthquake
GPS detection ionospheric perturbation El Salvador earthquake
2009/12/11
A large earthquake of M6.6 occurred on 13 February 2001 at 14:22:05 UT in El Salvador. We detected ionospheric perturbation before this earthquake using GPS data received from CORS network. Systematic...
The knowledge of the crustal strain rate tensor provides a description of geodynamic processes such as fault strain accumulation, which is an important parameter for seismic hazard assessment, as well...
Validation of landslide hazard assessment by means of GPS monitoring technique – a case study in the Dolomites (Eastern Alps,Italy)
Validation landslide hazard assessment GPS monitoring technique
2009/12/30
In the last years a research project aimed at the assessment of the landslide hazard and susceptibility in the high Cordevole river basin (Eastern Dolomites, Italy) have been carried out. The hazard m...
Mesoscale GPS Zenith Delay assimilation during a Mediterranean heavy precipitation event
Mesoscale GPS Zenith Delay assimilation Mediterranean precipitation event
2010/1/28
The impact of assimilating Zenith Total delay (ZTD) observations from a mesoscale ground-based GPS network over Western Europe is evaluated for the heavy precipitation event of 5–9 September 2005 over...
Impact of a high density GPS network on the operational forecast
a high density GPS network the operational forecast
2010/1/22
Global Positioning System Zenith Total Delay (GPS ZTD) can provide information about the water vapour in atmosphere. Its assimilation into the analysis used to initialize a model can then improve the ...
This work presents the first results of an experiment aiming to derive a high resolution Digital Terrain Model (DTM) by kinematic GPS surveying. The accuracy of the DTM depends on both the operational...
Assessment of two methods for gravity field recovery from GOCE GPS-SST orbit solutions
High-low SST gravity field GOCE variational equations least squares adjustment
2010/1/22
In the course of the GOCE satellite mission, the high-low Satellite to Satellite Tracking (SST) observations have to be processed for the determination of the long wavelength part of the Earth’s gravi...
