Model output for the MALI-SORRM simulations
收藏资源简介：
Description This dataset contains the model output in netCDF format from MPAS-Albany Land Ice (Hoffman et al., 2018) simulations of the Antarctic Ice Sheet from 2000-2100 for Shafer et al. (submitted). The output is composed of simulations that test how Antarctic mass loss responds when ice-shelf basal melt is parameterized using E3SMv2.1-SORRM (Comeau et al., 2025) thermal forcing (TF) either 1) within ice-shelf cavities ("cavity") or 2) extrapolated from the ice-shelf calving front ("open ocean"). We run five simulations for each experiment, one control and 4 projections using TF described here (https://doi.org/10.5281/zenodo.20388987).

## 数据集说明 本数据集包含针对Shafer等人（已投稿）的研究，由MPAS-Albany冰盖模型（MPAS-Albany Land Ice，Hoffman等，2018）对2000-2100年南极冰盖开展的模拟所生成的netCDF格式模型输出结果。该输出由多组模拟实验构成，用于测试当采用E3SMv2.1-SORRM（Comeau等，2025）的热强迫（thermal forcing, TF）对冰架底部融化进行参数化时，南极冰量损失的响应特征；其中热强迫的设置分为两种场景：1）冰架空腔内（"cavity"），2）从冰架崩解锋面向外推估的开阔海域（"open ocean"）。每组实验均开展5组模拟，包括1组对照模拟与4组基于本文所述热强迫的预估模拟（详见https://doi.org/10.5281/zenodo.20388987）。 ## 文件结构 数据归档的组织结构如下： ├── cavity │ ├── ctrl_ensmean │ ├── projection_0701 │ ├── projection_0751 │ ├── projection_0801 │ └── projection_ensmean ├── input_files └── open_ocean ├── ctrl_ensmean ├── projection_0701 ├── projection_0751 ├── projection_0801 └── projection_ensmean 每个模拟任务包含以下文件： ├── albany_input.yaml ├── flux.nc ├── globalStats.nc ├── log.albany.0000.out ├── log.landice.0000.out ├── namelist.landice ├── output_tf.nc ├── regionalStats.nc ├── state.nc └── streams.landice 下述变量名的定义可查阅：https://github.com/MALI-Dev/E3SM/blob/develop/components/mpas-albany-landice/src/Registry.xml ### 各文件所含变量 flux.nc 所含变量：sfcMassBalApplied、floatingBasalMassBalApplied、groundedBasalMassBalApplied、fluxAcrossGroundingLineOnCells、calvingThickness、faceMeltingThickness、Time output_tf.nc 所含变量：xtime、floatingBasalmassBalAppliedTF、oceanismip6shelfMelt_zOcean、ismip6shelfMelt_3dThermalForcing state.nc 所含变量：thickness、xvelmean、yvelmean、basalTemperature、Time 本归档还包含初始条件文件： ├── AIS_4to20km_r01_20220907.regionMask_ismip6.nc ├── relaxed_10yrs_4km_open_ocean.20241130.nc ├── AIS_4to20km_r01_20220907_RACMO2.3p2_ANT27_smb_climatology_1995-2017_minus1_bare_land.nc └── relaxed_10yrs_4km_with_cavities.20241130.nc 其中relaxed_10yrs_4km_open_ocean.20241130.nc 包含开阔海域的掩码文件，relaxed_10yrs_4km_with_cavities.20241130.nc 包含冰架空腔的掩码文件。 ## 参考文献 1.
