Characterizing Arctic sea ice topography using high-resolution IceBridge data [0.03%]
利用高分辨率的冰桥数据来描述北极海冰地形特征

Alek Petty et al.
We present an analysis of Arctic sea ice topography using high resolution, three-dimensional, surface elevation data from the Airborne Topographic Mapper, flown as part of NASA's Operation IceBridge mission. Surface features in the sea ice ...
Brief Communication: Upper air relaxation in RACMO2 significantly improves modelled interannual surface mass balance variability in Antarctica [0.03%]
简短交流：在RACMO2中高空放松显著改善了南极模拟的年际表面质量平衡变率

The regional climate model (RCM) RACMO2 has been a powerful tool for improving surface mass balance (SMB) estimates from GCMs or reanalyses. However, new yearly SMB observations for West Antarctica show that the modelled interannual variabi...
Design and results of the ice sheet model initialisation experiments initMIP-Greenland: an ISMIP6 intercomparison [0.03%]
冰盖模式初始化试验(initMIP-格陵兰):ISMIP6比对计划的设计和初步结果
Heiko Goelzer,Sophie Nowicki,Tamsin Edwards et al.
Heiko Goelzer et al.
Earlier large-scale Greenland ice sheet sea-level projections (e.g., those run during the ice2sea and SeaRISE initiatives) have shown that ice sheet initial conditions have a large effect on the projections and give rise to important uncert...
Characterizing permafrost active layer dynamics and sensitivity to landscape spatial heterogeneity in Alaska [0.03%]
刻画阿拉斯加冰冻土活性层动力学及其对景观空间异质性的敏感性
Yonghong Yi,John S Kimball,Richard H Chen et al.
Yonghong Yi et al.
An important feature of the Arctic is large spatial heterogeneity in active layer conditions, which is generally poorly represented by global models and can lead to large uncertainties in predicting regional ecosystem responses and climate ...
A Decade of Variability on Jakobshavn Isbrae: Ocean Temperatures Pace Speed Through Influence on Mélange Rigidity [0.03%]
雅各布沙文冰川十年来的变化：海洋温度通过影响浮冰盘的刚度来控制冰流速度

Ian Joughin et al.
The speed of Greenland's fastest glacier, Jakobshavn Isbrae, has varied substantially since its speedup in the late 1990s. Here we present observations of surface velocity, mélange rigidity, and surface elevation to examine its behaviour o...
Seasonal to decadal variability in ice discharge from the Greenland Ice Sheet [0.03%]
格陵兰冰盖冰川排放的季节至十年变化
Michalea D King,Ian M Howat,Seongsu Jeong et al.
Michalea D King et al.
Rapid changes in thickness and velocity have been observed at many marine-terminating glaciers in Greenland, impacting the volume of ice they export, or discharge, from the ice sheet. While annual estimates of ice-sheet wide discharge have ...
Greenland Ice Mapping Project: Ice Flow Velocity Variation at sub-monthly to decadal time scales [0.03%]
格陵兰冰层测绘计划：亚月至十年时间尺度的冰川流速变化
Ian Joughin,Ben E Smith,Ian Howat
Ian Joughin
We describe several new ice velocity maps produced by the Greenland Ice Mapping Project (GIMP) using Landsat 8 and Copernicus Sentinel 1A/B data. We then focus on several sites where we analyse these data in conjunction with earlier data fr...
