Mean Sea-level Rise Uncertainties
Intro
Many uncertainties
Biases drift estimated create adjusted GMSL rates that are accelerated :
VLM estimates mades positive bias drift and an increases of 0.57 mm/yr high than unadjusted rates
Creation of Figure 3
Many sensitivity tests eliminated cetain TG network and altimeter data
Unadjusted GMSL trend estimates CU data were within 0.02 mm/ yr−1 and 0.018 mm yr/−2 of our results, and adjusted estimates were within 0.06 mm yr−1 and 0.004 mm yr−2.
more sensitivty tests(multimission ensemble and misclosure analysis) were taken
20% higher weighted CP were removed because weren't sensitive enough
1.5 years of removed data decreased A bias drift
Creation of Figure 1
use an epanded network of tidal gauges(TG)
bias drift and residual ocean tide at many comparison points were found
Corrected bias drift by using new expanding GPS station data
modeled co seismic earthquake deformation to not include TG with vertical motion above specific threshold
Creation of Figure 2
shows adjusted and unadjusted satellite altimeter (GMSL)time series
BIas drift results show non-zero rates
previous deacceleration became acceleration
Application of different VLM estimtes positive bias drift
GPS VLM corrected because elastic deformation
Conclusion/Discussion
There should be more research to estimate bias drifts and issues of them
Archived altimeter data shoudn't be with found bias drift but GMSL estimaters should be aware of potential need to adjust for small significant bias in early data
