Replication Data for "Integration of GPS and InSAR Data for Resolving 3-Dimensional Crustal Deformation"

The supporting information dataset includes a sample run of the software gic3dv.f to combine the GPS and InSAR data for a 3-D velocity solution. The GPS velocity data are from a combination of the solutions from the continuous GPS network from the MEaSUREs project (ftp://sopac-ftp.ucsd.edu/pub/timeseries/measures/ats/WesternNorthAmerica/) and the campaign GPS network from the CMM4 project (Shen et al., 2011). The InSAR data are the LOS rate estimates of 4 tracks of ERS/Envisat measurements, averaged at 0.02 x 0.02 degree grids. The solution is for model A, with the following parameterization: (a) the estimated LOS rate data uncertainties are used for InSAR data weighting, (b) both the offsets and ramps are estimated for SAR satellite orbital errors, and (c) the GPS vertical data are not used to constrain the final pixel by pixel solution.
