GPS coordinate timeseries for bedrock displacements in East Antarctica, 2006-2019

Full description

Coordinate time series, in local topocentric east, north, up reference frame. 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 http://www-gpsg.mit.edu/~tah/GGMatlab/
# and described in Herring, T. MATLAB Tools for viewing GPS velocities and time series. GPS Solutions 7, 194–199 (2003). https://doi.org/10.1007/s10291-003-0068-0
#
# For each site, there are three files, ones for each of North, East and Up.
# For example, for site bhil
# mb_bhil_NEh.dat1 is for the North component
# mb_bhil_NEh.dat2 is for the East component
# mb_bhil_NEh.dat3 is for the Up component
#
# each file contains three header lines followed by the data with one row per epoch, such as
# 1995.1020 0.03150 0.00400
# with column 1 in decimal years, column 2 is the estimate (north, east or height) in metres, and column 3 is the uncertainty (1 sigma) of the measurement in metres
#
# North, East and Up are relative displacements and are not absolute coordinates
#
# Data for eight GPS sites are included in the archive, with approximate site coordinates:
# SiteID, lat (decimal degrees), lon (decimal degrees), site geographical location
