containing time series of geocenter pressure terms from global barometric fields at 6h interval, starting September 1, 1993 and ending April 30, 1997.
Since I am working on 3D atmospheric loading effects on GPS and VLBI sites, the geocentre data is some sort of crumbs from the table. Maybe it's of use to somebody out there.
Here's a piece of the data:

To obtain geocenter displacement in millimetre, multiply by -0.4418.
The units in the file are hectopascal times a factor 4pi/3 due to the integration over the sphere.
10^5*G*R/g^2 = 0.4418 mm/hPaQuestions, comments and complaints to Hans-Georg Scherneck
