Watson et al.
Discussion
more work needed
Matches ice sheet loss
adjustments needed for biases
bias drift likely variable
Topex degredation
more gps needed
longer time series needed
more, careful validation needed
method
satellite era time series of gmsl
seminal climate data record
quantifies and describes one of the most important manifestations of climate change
provides accurate estimates and projections of sea level rise
allows for infrastructure planning for potentially hit areas
gps
new approach
vertical land movement correction
helps with bias drift
daily time series
satellite data
OSTM/Jason-2
new measurements
post processing
Jason-1
sea surface height
radiometric correction
post processing
TOPEX/Poseidon
Sea surface height
post processing
Tide gauges
122 total, 96 after qc
validates satellites
aids bias drift
hourly data
residual ocean tide
GRACE mission measurements
elastic effects
Earthquake threshold
used to filter TGs
Glacial isostatic adjustment
vlm
results
bias drift identified
non-zero rates
largest found within TOPEX side A
small in OSTM
ALL significantly non-zero
sensitive to applied VLM
moderate in Jason-1
acceleration: 0.041
fixed GMSL rate: 2.6-2.9
lower than previously estimated
intro (previous)
GMSL(global mean sea level) rise
seen to be lower for the past decade
differ due to natural variability
estimations
do not include bias drift
does not include gps estimates of vertical land movement
lack of identification of significant non=zero systematic drifts
various vlms used
