INGV

The Istituto Nazionale di Geofisica e Vulcanologia was born in September 1999 through a merger of former Istituto Nazionale di Geofisica, Osservatorio Vesuviano and three other institutions: Istituto Internazionale di Vulcanologia, Istituto di Geochimica dei Fluidi and Istituto di Ricerca sul Rischio Sismico. INGV was meant to gather all scientific and technical institutions operating in Geophysics and Volcanology and to create a permanent scientific forum in the Earth Sciences. INGV cooperates with universities and other national public and private institutions, as well as with many research agencies worldwide. The new institution, currently the largest European body dealing with research in Geophysics and Volcanology, has its headquarters in Rome and important facilities in Milano, Bologna, Pisa, Napoli, Catania and Palermo. The main mission of INGV is the monitoring of geophysical phenomena in both the solid and fluid components of the Earth. INGV is devoted to 24-hour countrywide seismic surveillance, real-time volcanic monitoring, early warning and forecast activities.

Service

This service allows users to download GNSS velocities generated by the INGV analysis center.

The data can be filtered using search parameters such as coordinates and dates.

Reference Frame and Output Components

Velocities are provided with respect to a no-net-rotation global terrestrial reference frame. They are returned in the local components East (E), North (N), and Up (U), or alternatively in Cartesian components (X, Y, Z), together with the associated uncertainties:

• Standard deviations for each component (SE, SN, SU)
• Correlations between components (RNE, RNU, REU)

Table – shows all selected stations selected, including the following fields:

• GNSS Station ID; dn/dt; de/dt; du/dt; First epoch; Last epoch; Reference frame; software;

and can display these fields if they are selected (X):

• DOI; Release Version; Method URL; Unit; Reference epoch; ref_x; ref_y; ref_z; ref_nlat; ref_elong; ref_up; dx/dt; dy/dt; dz/dt; sxd; syd; szd; rxy; rxz; ryz; snd; sed; sud; rne; rnu; reu; M3G; DGW;
