Data accompanying the article "Atmospheric-river-induced foehn events drain glaciers on Novaya Zemlya"
Wat erin zit
The glacier volume of the High Russian Arctic ice cap on Novaya Zemlya has been declining since the Little Ice Age. However, in the recent period, the loss of glacial ice has accelerated. We studied the glacier mass loss drivers by comparing the output of the regional atmospheric model MAR with observations from CryoSat-2, GRACE/GRACE-FO, and ICESat, and reanalysis results from ERA5 and MERRA2. We found that additional moisture import marjorly drives the mass loss increase; with foehn winds steering the transported energy to the lee-slope glacier surface. Here, we publish time series of modeled surface mass fluxes and moisture transport from reanalysis from 1980 to 2022, glacier mass change time series from observational data for different periods between 2002 and 2022, and the CryoSat-2 derived glacier surface elevation trends from 2011 to 2022 at a 500-by-500 m resolution. This dataset contributes to the reproducibility of the results, and can be compared to future datasets or used for further research. The source data of CryoSat-2 derived products were provided by the European Space Agency (ESA).
