500-yr Projections of Thwaites Glacier, Antarctica, with MALI, including glacial isostatic adjustment
收藏资源简介：
This archive contains model code, results, and analysis scripts for<br> reproducing the material presented in the manuscript "Stabilizing effect of<br> bedrock uplift on retreat of Thwaites Glacier, Antarctica, at centennial<br> timescales" by Cameron Book, et al. Questions should be directed to Matt<br> Hoffman (mhoffman@lanl.gov). This archive contains the following directories: |-- MALI_code<br> |-- PIGL_control<br> |-- analysis<br> |-- control<br> |-- run_setup<br> |-- N1<br> |-- N2<br> |-- N3<br> |-- N4<br> `-- PIGL_N3 <br> 'MALI_code' is a snapshot of the MALI repository used for these simulations,<br> commit 454e0fc8bf384bee1c1560d6c3eaa5fae43bfdda.<br> This commit is present in an older MALI repository that is no longer<br> maintained, at https://github.com/MPAS-Dev/MPAS-Model<br> MALI is currently maintained on Github at https://github.com/MALI-Dev/E3SM<br> Building MALI requires the Albany multiphysics library, which is available<br> at https://github.com/sandialabs/Albany. The simulations presented use Albany<br> master from March 5, 2021. 'analysis' contains the scripts used to process the model output and produce<br> the figures and results presented in the manuscript. Filepaths will have to<br> be adjusted to your local layout. 'run_setup' is a directory of files and scripts necessary to reproduce the<br> model simulations presented. The GIA model giapy is in the file<br> 'giascript.py'. giapy can also be found on Github at https://github.com/skachuck/giapy 'control' is the control run with the GIA model disabled. It corresponds to<br> the run labeled CTRL in the manuscript. 'PIGL_control' is the control run using the high melt forcing. It corresponds<br> to the run labeled HM-CTRL in the manuscript. The five run directories included here (N1-N4, PIGL_N3) are the standard<br> ensemble described in the manuscript. (There is a separate archive for the<br> runs briefly mentioned that exclude the elastic response of the lithosphere.)<br> The individual runs have the following correspondence to the manuscript:<br> N1=TYP<br> N2=BEST2<br> N3=VLV-THIN<br> N4=VLV<br> PIGL_N3=HM-VLV-THIN<br> Within each run directory, are the following model output files:<br> globalStats.nc: MALI global, scalar time-series<br> iceload_all.nc: Thwaites Glacier ice load on the GIA grid<br> output_*.nc: MALI spatial output fields, separated by century<br> uplift_GIA_all.nc: GIA output on GIA grid
本归档包含用于复现论文《南极思韦茨冰川百年尺度退缩与基岩抬升的稳定效应》（原英文标题："Stabilizing effect of bedrock uplift on retreat of Thwaites Glacier, Antarctica, at centennial timescales"）的模型代码、结果与分析脚本，作者为Cameron Book等人。相关疑问请联系Matt Hoffman（邮箱：mhoffman@lanl.gov）。 本归档包含以下目录： |-- MALI_code |-- PIGL_control |-- analysis |-- control |-- run_setup |-- N1 |-- N2 |-- N3 |-- N4 `-- PIGL_N3 其中各目录说明如下： 1. MALI_code：为本研究数值模拟所用的MALI代码仓库快照，版本提交哈希为`454e0fc8bf384bee1c1560d6c3eaa5fae43bfdda`。该提交版本存放在已停止维护的旧版MALI仓库，地址为https://github.com/MPAS-Dev/MPAS-Model；当前MALI的官方维护仓库地址为https://github.com/MALI-Dev/E3SM。编译MALI需依赖Albany多物理场库，其源码地址为https://github.com/sandialabs/Albany。本研究模拟所用的Albany版本为2021年3月5日的master分支代码。 2. analysis：包含用于处理模型输出、生成论文中图表与结果的分析脚本。请根据本地文件布局调整脚本内的文件路径。 3. run_setup：包含复现本研究模型模拟所需的全部文件与脚本。其中冰川均衡调整（Glacial Isostatic Adjustment, GIA）模型giapy位于文件`giascript.py`中，giapy的源码可在https://github.com/skachuck/giapy获取。 4. control：为关闭GIA模型的对照模拟实验，对应论文中标记为CTRL的实验组。 5. PIGL_control：为采用高融水强迫的对照模拟实验，对应论文中标记为HM-CTRL的实验组。 6. 本次归档包含的5个模拟目录（N1至N4、PIGL_N3）为论文中所述的标准集合模拟实验（另有独立归档包含文中简要提及的、排除岩石圈弹性响应的模拟实验）。各模拟与论文标记的对应关系如下： N1=TYP N2=BEST2 N3=VLV-THIN N4=VLV PIGL_N3=HM-VLV-THIN 7. 每个模拟目录下均包含以下模型输出文件： - `globalStats.nc`：MALI全局标量时间序列数据 - `iceload_all.nc`：GIA网格上的思韦茨冰川冰负荷数据 - `output_*.nc`：按世纪分隔的MALI空间输出场数据 - `uplift_GIA_all.nc`：GIA网格上的抬升输出数据
