ACT-America: WRF-Chem Baseline Simulations for North America, 2016-2019

This dataset includes hourly output from the WRF-Chem simulation model for North America at a resolution of 27 km for 2016-06-29 through 2019-07-31. WRF-Chem is the Weather Research and Forecasting (WRF) model coupled with Chemistry. The output provides baseline conditions for comparison to data from ACT-America airborne campaigns conducted to study atmospheric CO2 and CH4 from 2016 to 2019. The WRF-Chem (v. 3.6.1) model was driven by meteorological conditions and sea-surface temperatures. The output includes 50 vertical layers up to atmospheric pressure of 50 hPa with 20 levels in the lowest 1 km. It provides information for understanding the fluxes and atmospheric transport of carbon dioxide (CO2), methane (CH4), and ethane (C2H6).

本数据集包含2016年6月29日至2019年7月31日期间，针对北美地区以27公里分辨率的WRF-Chem（天气研究预报模型与化学耦合）模拟模型的每小时输出结果。WRF-Chem模型系将天气研究预报模型（WRF）与化学模块相结合而成。输出数据提供了基准条件，以便与2016年至2019年间为研究大气二氧化碳（CO2）、甲烷（CH4）和乙烷（C2H6）的ACT-America空中作业数据进行比较。WRF-Chem（版本3.6.1）模型的运行受气象条件和海面温度驱动。输出结果包括直至50 hPa大气压力的50个垂直层，其中最低1公里的垂直层划分为20个水平层次。该数据集提供了理解二氧化碳（CO2）、甲烷（CH4）和乙烷（C2H6）的通量和大气传输信息。
