Tasks of Work Package 2
Last edited 29 January 2004
T2.1: Define, implement and validate a CGPS processing strategy (P1,
P4, P7, P9, P12, P16, P20), with special emphasis on the vertical
component, which will enable the determination of vertical station
velocities in a consistent reference frame with an accuracy of 1mm/yr.
T2.2: Define, implement and validate a strategy for the analysis of CGPS time series
(P1, P4, P16, P20), which will enable the determination of vertical station velocities in a consistent reference frame with an uncertainty of less than 0.5mm/yr.
T2.3: Carry out a coherent processing of all observations from CGPS stations co-located with ESEAS Observing Sites, based on the strategy developed in T2.1 (P1, P4, P7, P9, P20).
T2.4: Assemble information on physical parameters that may affect CGPS time series, eg ocean tide loading, atmospheric pressure loading and hydrological loading (P1, P4, P18, P20).
T2.5: Carry out a coherent analysis of the time series from CGPS
stations co-located with ESEAS Observing Sites, based on the strategy
developed in T2.2 (with input from T2.4) (P1, P4, P20).
T2.6: Carry out absolute gravity measurements at selected ESEAS Observing Sites (P3, P20).
T2.7: Assemble information on (historical and current) precise levelling at all ESEAS Observing Sites that are co-located with CGPS stations (P4, P9, P11, P12, P16, P18, P20).
T2.8: Assess the contribution of vertical land movements and absolute sea level variations to changes in relative sea level, using the results from T2.5 in conjunction with T2.6 and T2.7
(all involved partners).
