ARtracks - a Global Atmospheric River Catalogue Based on ERA5 and IPART

The ARtracks Atmospheric River Catalogue is based on the ERA5 climate reanalysis dataset, specifically the output parameters "vertical integral of east-/northward water vapour flux". Most of the processing relies on IPART (Image-Processing based Atmospheric River (AR) Tracking, https://github.com/ihesp/IPART), a Python package for automated AR detection, axis finding and AR tracking. The catalogue is provided as a pickled pandas.DataFrame as well as a CSV file. For detailed information, please see https://github.com/dominiktraxl/artracks. The ARtracks catalogue covers the years from 1979 to the end of the year 2019.ARtracks大气河目录基于ERA5气候再分析数据集，核心采用其输出参数“东向与北向水汽通量的垂直积分量”。该目录的绝大多数处理流程依托IPART（基于图像处理的大气河（Atmospheric River, AR）追踪工具，其GitHub仓库地址为https://github.com/ihesp/IPART）——这是一款可实现自动化大气河检测、轴线识别与追踪的Python工具包。本目录以经pickle序列化的pandas.DataFrame格式与CSV文件两种形式提供。如需获取详细信息，请参阅https://github.com/dominiktraxl/artracks。该目录的时间覆盖范围为1979年至2019年年末。

背景与挑战

背景概述

ARtracks是一个全球大气河流目录，基于ERA5气候再分析数据和IPART Python包自动检测与追踪大气河流，覆盖1979年至2019年。数据集以CSV和pickle格式提供，用于研究大气河流的时空特征、动态和自然灾害关联。
