GPS coordinate timeseries for bedrock displacements in East Antarctica, 2006-2019
Listed in NASA Earthdata CMR
Coordinate time series, in local topocentric east, north, up reference frame.
Description
Underlying coordinates were derived in IGS14 reference frame. Coordinate time series generated using GIPSY6.3 using NASA JPL clocks and orbits from repro2 as operational circa 2020. # The files available are geodetic GPS coordinate time series for bedrock displacements # for a range of sites in East Antarctica.
They were collected under AAS4318. Data should only be used when appropriately cited. # The Coordinates were estimated using GIPSYv6.3 using JPL repro2 clocks and orbits # # Data are in TSVIEW format, a simple ascii file format # TSVIEW is an open Matlab code for visualising and analysing GPS time series but the series can be easily read by other software # TSVIEW is available at www-gpsg.mit.edu/~tah/GGMatlab/ # and described in Herring, T. MATLAB Tools for viewing GPS velocities and time series.
