Hourly Stratospheric Tracer Simulation Data based on WRF-Chem (May 2024)

This dataset provides high-resolution, hourly simulation results of stratospheric tracers for the entire month of May 2024. The simulations were conducted using the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem). The spatial domain primarily covers East Asia (spanning 6.97°N to 49.42°N and 67.06°E to 150.94°E), encompassing China and its surrounding regions.The dataset consists of 745 NetCDF (.nc) files. Key variables included are geographic coordinates (XLAT, XLONG), simulation timestamps (XTIME), and a specific stratospheric passive tracer. Passive tracers are utilized to track the transport and intrusion of stratospheric air masses into the troposphere.This dataset is designed to support research on Stratosphere-Troposphere Transport (STT), ozone downward transport, and the impact of stratospheric air on regional air quality and atmospheric chemistry dynamics in East Asia.

本数据集提供了2024年5月整月的平流层示踪剂高分辨率逐小时模拟结果。此项模拟采用耦合化学模块的天气研究与预报模型（Weather Research and Forecasting model coupled with Chemistry，简称WRF-Chem）完成。模拟空间域主要覆盖东亚区域（纬度范围6.97°N至49.42°N，经度范围67.06°E至150.94°E），包含中国及其周边区域。本数据集共包含745个NetCDF格式（.nc）数据文件。核心变量包括地理坐标（XLAT、XLONG）、模拟时间戳（XTIME）以及特定平流层被动示踪剂。被动示踪剂用于追踪平流层气团向对流层的输送与侵入过程。本数据集旨在支撑东亚地区平流层-对流层输送（Stratosphere-Troposphere Transport，简称STT）、臭氧向下输送，以及平流层空气对区域空气质量与大气化学动力学影响相关的研究工作。
