Data
Sea level rise from the Antarctic Ice Sheet since January 1979 (IMBIE)
How much the Antarctic Ice Sheet's loss of ice has added to global mean sea level each month from January 1979 to December 2023, from the IMBIE team's reconciliation of satellite surveys, with the one-sigma uncertainty. IMBIE converts 360 Gt of ice to 1 mm of sea level.

What was done to it
Read the 'Cumulative mass balance anomaly (mm)' column and its uncertainty from imbie3_antarctica_mm_partitioned.csv (IMBIE version 1.0), 1979-01 to 2023-12.

Checked every month against imbie3_antarctica_Gt_partitioned.csv: the mm value and its uncertainty equal the Gt values divided by 360 (IMBIE's 360 Gt of ice per mm of sea level), so the mm column has the mass-balance sign, negative for a loss of ice.

Flipped the sign, so that a positive value is a rise in global mean sea level. Lower and upper are the flipped value minus and plus the one-sigma uncertainty.

What it covers
- Geography
- Antarctic Ice Sheet (West and East Antarctica and the Antarctic Peninsula)
- Baseline
- Zero just before January 1979, the start of IMBIE's Antarctic record; the first month's value is that month's change.
- Basis
- Reconciled from 21 independent satellite estimates (altimetry, gravimetry and the input-output method) by IMBIE 2026; total mass balance, the sum of surface mass balance and ice dynamics. Positive values raise global mean sea level; 360 Gt of ice = 1 mm.
- Unit
- millimetres (mm)
