ATom: CAM-chem/CESM2 Model Outputs Along Flight Tracks, 2016-2018

This dataset contains CAM-chem (Community Atmosphere Model with Chemistry) model outputs along ATom flight tracks. CAM-chem is a component of the Community Earth System Model Version 2 (CESM2) and is used for simulations of global tropospheric and stratospheric atmospheric composition and for studies of chemistry-climate interactions. In general, CAM-chem uses the MOZART chemical mechanism, with various choices of complexity for tropospheric and stratospheric chemistry. For this dataset, CAM-chem used the MOZART-TS1 chemical mechanism, and the model was nudged to reanalysis meteorology from MERRA2.

本数据集包含大气化学耦合模式（CAM-chem，Community Atmosphere Model with Chemistry）的模式输出结果，以及沿ATom飞行轨迹的配套数据。大气化学耦合模式是地球系统模式第2版（CESM2，Community Earth System Model Version 2）的组成模块，可用于全球对流层与平流层大气成分的模拟，以及化学-气候相互作用相关研究。通常情况下，大气化学耦合模式采用MOZART化学机制，并可针对对流层与平流层化学过程选用不同复杂度的模拟方案。本数据集所使用的大气化学耦合模式采用了MOZART-TS1化学机制，且模式气象场通过张弛同化方法被约束于MERRA2再分析气象数据。
