Fig. 1: Glacier mass change time series.
From: Atmospheric-river-induced foehn events drain glaciers on Novaya Zemlya
The mass change of the ice cap on Novaya Zemlya since 1 January, 1980, derived from the Input-Output (I/O) model. We include observations from GRACE/GRACE-FO22, ICESat12, and CryoSat−2 for which we chose arbitrary starting points such that the differences to each other are minimized but retain a 50 Gt-offset to the I/O time series to declutter the plot. The dashed lines show least-square regression results of the I/O data for the periods 1981 to 2010 and 2011 to 2022 and of the CryoSat−2 data for 2010 to 2022. The colored patches along the I/O time series quantify the prevailing negative glacier mass balance (MB) for glaciological years, i.e., starting 1 October; those are aggregated into the inset histogram. Source data are provided as a Source Data file.
