What was done to it

  1. Read the 'Cumulative mass balance anomaly (Gt)' column of imbie3_greenland_Gt_partitioned.csv (IMBIE version 1.0), 1971-07 to 2023-12, as printed.

    Code: pipeline/src/envdash/transforms/ice/imbie_2026.py · code sha256 890ecd9e82cc65eb… · inputs 1d4df7c73845…

  2. Lower and upper are the value minus and plus the file's 'Cumulative mass balance anomaly uncertainty (Gt)', which the file states is one standard deviation (exact decimal arithmetic).

What it covers

Geography
Greenland Ice Sheet
Baseline
Zero just before July 1971, the start of IMBIE's Greenland record; the first month's value is that month's change.
Basis
Reconciled from 24 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.
Unit
gigatonnes (Gt)
