CAM-chem Model Outputs used in "Measurement Report: Characterization of Aerosol Hygroscopicity over Southeast Asia during the NASA CAMP2Ex Campaign"

The Community Atmosphere Model coupled with chemistry (CAM-chem) is a component of the Community Earth System Model (CESM2.2) that represents the dynamics, physics, and chemistry of the atmosphere. The Multi-Scale Infrastructure for Chemistry and Aerosols (MUSICA) is a configuration of CAM-chem, it is a next generation unified infrastructure to study atmospheric chemistry at different horizontal grid resolutions. It is community-built, open-source, flexible, and computationally efficient.Our data includes different horizontal resolutions of CAM-chem and MUSICA version 0. The available regional refined grids were created by users for a variety of applications. We used a 1º base grid resolution (ne30) and a 0.25º (ne30x4) regionally refined output grid (which we label MUSICA) for East Asia that was developed at the NSF National Center for Atmospheric Research (NCAR)/Atmospheric Chemistry Observations and Modeling Laboratory (ACOM).

化学耦合社区大气模式（Community Atmosphere Model coupled with chemistry, CAM-chem）是社区地球系统模型（Community Earth System Model, CESM2.2）的组成模块，用于表征大气的动力过程、物理过程与化学过程。化学与气溶胶多尺度基础设施（Multi-Scale Infrastructure for Chemistry and Aerosols, MUSICA）是CAM-chem的一类配置方案，是可用于研究不同水平网格分辨率下大气化学过程的下一代统一基础设施，具备社区共建、开源灵活、计算效率优异的特点。本数据集包含不同水平网格分辨率的CAM-chem与MUSICA 0版本数据。其中可用的区域加密网格由用户针对各类应用场景构建。本研究采用了1°基准网格分辨率（ne30），以及由美国国家科学基金会（National Science Foundation, NSF）下属国家大气研究中心（National Center for Atmospheric Research, NCAR）大气化学观测与模拟实验室（Atmospheric Chemistry Observations and Modeling Laboratory, ACOM）开发的、针对东亚区域的0.25°（ne30x4）区域加密输出网格（本研究将其标记为MUSICA网格）。
