Mass balance of the Greenland Ice Sheet
01 Feb 2016–31 Jan 2018 | Guest editors: M. Tedesco, I. M. Howat, E. Hanna, L. Koenig, I. Velicogna, and J. Bamber | Information

The mass balance of the Greenland Ice Sheet (GrIS) is crucial for quantifying and properly projecting its contribution to sea level rise as well as to understand the implications of changes in both surface mass balance and ice dynamics in the Arctic system (e.g. impact on atmosphere, ocean, etc.). Over the past years, an increasing number of scientific efforts have been focusing on improving estimates of the mass balance of the GrIS and the physical processes driving such changes. The increasing number of ad hoc observations, both in situ and from airborne and spaceborne platforms, as well as the increasing complexity of regional and global climate models, ice sheet models, and physics parameterizationimplemented there have been catalyzing research activities and the amount of scholarly work focusing on the GrIS.

The goal of this special issue (SI) in The Cryosphere is to provide a venue for collecting papers focusing on the mass balance of the GrIS, with the gal of consolidating the current knowledge and state of the art of the scientific activities on the topic in an open-access, highly accessed, and community oriented journal, such as The Cryosphere. To our knowledge, no such effort has been made since the last PARCA activities, more than 2 decades ago. In view of this, we invite contributions focusing on results addressing the mass balance of the GrIS. The focus of the SI is on (though not limited to) the following: 1) papers specifically focusing on both the surface mass balance (SMB) as well as the ice dynamics of the GrIS, and their interaction, using insitu or remote sensing observations, modelling tools, and the combination of the two; 2) experiments and results addressing the issue of reducing uncertainties on mass balance estimates; 3) the application of novel techniques; 4) “synthesis” papers summarizing the most current methods, results, and applications concerning estimates of the mass balance of the GrIS. Studies generally focusing on the mass balance of the GrIS are also strongly encouraged.

Changing Permafrost in the Arctic and its Global Effects in the 21st Century (PAGE21) (BG/TC/GMD/ESSD inter-journal SI)
01 Jan 2016–31 Dec 2017 | Guest editors: S. Gruber, J. Boike, and S. Lamoreux | Information

Permafrost is defined as ground that remains continuously at or below 0°C for at least two consecutive years; some 24% of the land surface in the Northern Hemisphere is classified as permafrost. In the northern high latitudes, strong warming has been observed over the recent decades, and climate models project strong future warming. A projected decline in the extent of permafrost will have a major impact on the Earth system, affecting global climate through the mobilization of carbon and nitrogen stored in permafrost. This special issue invites results of the large-scale European project PAGE21 with the aim to quantify the vulnerability of permafrost environments to a changing global climate, and to investigate the feedback mechanisms associated with increasing greenhouse gas emissions from permafrost zones. The focus is on (i) the combination of field mapping and measurements of permafrost landforms, ground ice content, processes, pools, and fluxes, with remote sensing data and global climate models at local, regional, and pan-Arctic scales, as well as (ii) advancing our understanding of permafrost processes at multiple scales, resulting in improvements in global numerical permafrost modeling.
