Fig. 3 Temporal variation of pressure anomalies and modeled vertical displacements at stations
Wettzell (Germany) and Fortaleza (Brazil) from 2005.0 to 2010.0
a particular area depends primarily on geographical latitude and proximity to the
oceans where the inverted barometer (IB) effects are significant. It can be seen that
variations of pressure anomaly at mid-latitudes are large and, therefore, the effects
of APL in this region are more dominant than those in other regions.

vertical displacements for the two geodetic stations Wettzell, Germany (49
