Greenland Ice Sheet modeled firn properties from SNOWPACK and the Community Firn Model (1980-2020)

This dataset contains model output from the physics-based SNOWPACK firn model and the semi-empirical Community Firn Model (CFM) over the Greenland Ice Sheet from 1980 through 2020. Included are individual density profiles for locations with firn density observations as well as firn air content (FAC) calculated over different depth intervals. Data for both models are supplied. These data are used in a manuscript to be submitted to The Cryosphere journal (see Thompson-Munson et al., in review).本数据集收录了1980至2020年格陵兰冰盖范围内，基于物理过程的SNOWPACK粒雪模型（SNOWPACK firn model）与半经验社区粒雪模型（Community Firn Model，CFM）的模拟输出结果。数据集包含具备粒雪密度观测记录的点位对应的单条密度剖面，以及不同深度区间计算得到的粒雪含气量（firn air content, FAC）。两款模型的相关数据均已提供。上述数据将用于一篇投稿至《冰冻圈》（The Cryosphere）期刊的研究论文，详见Thompson-Munson等（审稿中）。
