The Air Pressure Loading home page

Here you can obtain time-series of surface displacement due to atmospheric pressure loading.
The data come as 6 h samples of 3D local surface displacement (Vertical, East, North).
We offer data for the following categories of stations

Periods 
 A  GPS Nordic GPS stations, European IGS continuously after Aug 1993
 B  VLBI  NASA R&D, Europe, NEOS selected experiments 1993-1997
 C  VLBI NASA R&D, Europe, NEOS selected experiments 
1989-1993
 D  VLBI CORE networks 1997--
The format for the time series is pretty obvious: 

#1   1996jan01:00   -.00226    .00126    .00075
#2   1996jan01:06   -.00218    .00145    .00070
#3   1996jan01:12   -.00129    .00129    .00089
#4   1996jan01:18   -.00158    .00146    .00088
#1   1996jan02:00   -.00153    .00136    .00084
#2   1996jan02:06   -.00193    .00140    .00067
#3   1996jan02:12   -.00130    .00109    .00085

#n   yyyymmmdd:hh      DR         DE        DN

DR, DE, DN = Radial (vertical), East, and North displacement, respectively.
Units = metre
The consequent increase of dates in the file cannot be
guaranteed.
The long-term average offset for each station (which is to be subtracted in order to obtain continuity with analyses that are uncorrected for air pressure loading ) is available here for each category:  A   B   C   D  The mean is computed from all the fields from Aug 1993 through Sep 1997.

Associated solid earth centre of mass time-series are available for the period from Aug 1993 through Sep 1997.  Refer to the  special document
