INTERNATIONAL CENTER FOR EARTH TIDES (ICET)

Director: Jean-Pierre Barriot

See below for an important notice on change of ICET location!

 

1. Objectives

The International Center for Earth Tides (ICET) is a permanent service within the Federation of Astronomical and Geophysical Data Analysis Services (FAGS) and  is the World Data Center C for Earth Tides. It is hosted by the Observatoire Royal de Belgique (ORB). ICET is the International Data Center of the Global Geodynamics Project (GGP).

2. Summary of Data Held

Data from 360 worldwide tidal gravity stations: hourly values, main tidal waves obtained by least squares analyses, residual vectors, oceanic attraction and loading vectors. The Data Bank contains also data from tiltmeters and extensometers. ICET is the International Data Center of the GGP Project, a world wide network of continuously recording superconducting gravimeters.

3. Data Products, Publications, Catalogues

The Bulletin d'Informations Marees Terrestres is published two or three times a year. The already published more than 10000 pages contain a great number of translations of Russsian and some Chinese papaers. A General Bibliography on earth tides with 5027 references is also regularly maintained.

4. User Services

ICET provides assistance for the setup of new earth tide stations, calibrations of the instruments, data processing as well as for earth tide analysis. The assistance is accomplished either by a stay at ICET or by providing FORTRAN programs. ICET makes also available earth tide predictions for any place and time, which are needed for field gravimetry, absolute gravity measurements and for tilt measurments. These predictions can be computed either on the basis of elastic Earth models and oceanic cotidal maps, or on the basis of analyis results from existing earth tide observations.
