Iberian atmospheric river detection catalogue based on ERA5 reanalysis data

This dataset contains an atmospheric river (AR) catalogue created for the publication Luís et al. (2025), "Atmospheric Rivers in the Iberian Peninsula: Connection with Extratropical Fronts and Precipitation", Journal of Geophysical Research: Atmospheres, 130, e2025JD043891 (https://doi.org/10.1029/2025JD043891). The associated methodology is described in this publication. The dataset provides information on the persistent ARs that affected the Iberian Peninsula, in the period 1979-2020, based on ERA5 reanalysis data with 6-hour time resolution and 0.25° x 0.25° spatial resolution.本数据集包含为路易斯（Luís）等人2025年发表于《地球物理研究杂志：大气科学（Journal of Geophysical Research: Atmospheres）》第130卷、论文编号e2025JD043891（DOI: 10.1029/2025JD043891）的研究论文《伊比利亚半岛的大气河流：与温带锋面及降水的关联》所制作的大气河流（Atmospheric River，AR）目录。相关研究方法已在该论文中详细说明。 本数据集基于时间分辨率为6小时、空间分辨率为0.25°×0.25°的ERA5再分析数据，提供了1979年至2020年间影响伊比利亚半岛的持续性大气河流的相关信息。
