Reconstructed Ice-Sheet Thickness Time Series (Lower 95% Confidence Bound), 20 ka to Present

Lower 95% confidence bound (2.5th percentile) of the bootstrap-derived ice-sheet thickness ensemble for each site retained in the final thinning-history reconstruction. Each row gives site number, age (years before present), reconstructed ice thickness (m), and site coordinates in EPSG:3031 polar stereographic projection (meters). Data are provided at native model resolution (2-year timesteps) from 20,000 years ago to present. This file reports the lower bound of the reconstructed thickness ensemble; companion files report the posterior mean and upper 95% confidence bound (97.5th percentile), together characterizing the full uncertainty envelope at each site and timestep.
