Results of "Comparison of ice dynamics using full-Stokes and Blatter-Pattyn approximation: application to the Northeast Greenland Ice Stream"

This archive provides ice sheet model output produced as part of the publication: Rückamp, M., Kleiner, T., and Humbert, A.: Comparison of ice dynamics using full-Stokes and Blatter–Pattyn approximation: application to the Northeast Greenland Ice Stream, The Cryosphere, 16, 1675–1696, https://doi.org/10.5194/tc-16-1675-2022, 2022. About the data: The archive contains 2 zipped tar-files for the two 2 different regions 'icestream' and 'outlet'. Each tar-file contains ascii files for the different conducted scenarios. An exemplary filename looks like: FSvsBPlike_icestream_res12800m_E1_SlidingM1_isFS_P1P1GLS_BCstrong.txt 'FSvsBPlike' indicates the general study 'icestream' indicates the region (either icestream or outlet) 'res12800m' indicates the horizontal resolution (ranges from 12800 to 100 meter) 'E1' indicates the enhancement factor used (available values E=0.1, 1, 3 and 6) 'SlidingM1' indicates the employed sliding exponent (available values m=1 and 3) 'isFS' indicates that the full-Stokes equation was employed (either isFS or isBPlike) 'P1P1GLS' describes the employed finite element discretization (either P1P1GLS or P2P1) 'BCstrong' indicates that the strong basal boundary implementation was used (either BCstrong or BCweak) An exemplary file structure looks as follows: % Creation date: 03-May-2022 % Institution: AWI (Bremerhaven-Germany), BADW (Munich-Germany) % Correspondence: Martin Rueckamp ([e-mail]), Angelika Humbert ([e-mail]) % Source: COMSOL version 5.6 (www.comsol.com) % Citation: Rückamp et al.

The fields x, y contain x- and y coordinates of the grid nodes in EPSG:3413 projection. The fields z_s and z_b are the ice surface and ice base, respectively. The fields vx, vy, and vz are the ice velocities in horizontal (x,y) and vertical (z) direction. The field p is the pressure. The subscripts _s and _b indicate the surface and ice base, respectively.
