Data format:
GR_NASA_ICEBRIDGE_WGS84_ATM_2015_04_18.H5
HDF5 file with seasonal elevation data from 2015 NASA Operation IceBridge campaign (Southwest Coastal A). Contains co-registered triangulated data from 10 days in Fall 2015.
GR_NASA_ICEBRIDGE_WGS84_ATM_2015_05_05.H5
HDF5 file with seasonal elevation data from 2015 NASA Operation IceBridge campaign (IceSat-2 North / CryoSat-2 SARI). Contains co-registered triangulated data from 7 days in Fall 2015.
GR_NASA_ICEBRIDGE_WGS84_ATM_2016_05_14.H5
HDF5 file with seasonal elevation data from 2016 NASA Operation IceBridge campaign (Land Ice SW Coastal A). Contains co-registered triangulated data from 8 days in Fall 2016.
Triangulated data is stored in groups based on the instrument and acquisition date (INST_YYYY-MM-DD)
HDF5 data variables:
elev: Surface elevation [m]
error: Elevation error [m]
lon: Longitude of measurement [degrees east]
lat: Latitude of measurement [degrees north]
time: Acquisition time measured as seconds elapsed since January 1, 2000 12:00:00 UTC (J2000 seconds)
ITRF: Offset due to changes in reference frame at the measurement position at the acquisition time [m]
gia_uplift: GIA induced crustal uplift rate from a combination of coefficients from Simpson et al. (2009) [m/yr]
gia_error: Estimated GIA crustal uplift rate error calculated from RMS of coefficients from Simpson et al. (2009) [m/yr]
tide_load: Tidal elevation from TPXO7.2 harmonic constants at the measurement position at the acquisition time [m]
tide_pole: Solid Earth pole tide displacements at the measurement position at the acquisition time [m]
IQR: Mask calculated using a interquartile range algorithm (Pritchard et al., 2009)
RDE: Mask calculated using a robust dispersion estimator algorithm (Smith et al., 2017)
Geophysical corrections need to be subtracted from the elevation measurements
ITRF offsets need to be added to the elevation measurements
