Supplementary data for "Seasonal emergence and circulation coupling of moist layers over the tropical Atlantic"

The data provided here contains the derived moist layer characteristics from ERA5 reanalysis, as presented in the associated publication. Data is given on a 0.25° latitude/longitude grid between 30°N/S on the native vertical levels of the ERA5 dataset, cut off at 50 hPa. When a moist layer is detected at a given location and altitude, as identified by the method described in Sect. 2.2 of the publication, the moist layer characteristics (strength, pressure level, upper bound pressure, lower bound pressure) are written in the associated files at the given location (lat/lon) and pressure level of the moist layer. Here, we provide the 15 year means and standard deviations for the months January and July, and the 3 hourly data along the equatorial and 15°N cross-sections of the Atlantic used for the Hovmoller diagrams in Fig. 4 and Supporting Figure S1 of the publication.

Files containing "geographical_mean" indicate monthly means on the latitude/longitude grid. Files containing "moisture_space" indicate monthly means within moisture space over the tropical Atlantic, as defined in the paper. Code used to generate the data and to conduct the analysis presented in the publication are provided in the github repository URL listed in the Software section.

本数据集包含源自ERA5再分析资料（ERA5 reanalysis）的衍生湿层特征数据，相关成果已发表于对应学术出版物。数据采用0.25°经纬度网格分辨率，覆盖南北纬30°区域，使用ERA5数据集的原生垂直层级，截断气压为50 hPa。当依据论文第2.2节所述方法，在特定位置与高度检测到湿层时，湿层的特征参数（强度、气压层级、上限气压、下限气压）将被写入对应文件，存储于该湿层所在的经纬度位置与湿层所属的气压层级处。
本次发布的数据包含15年尺度下1月与7月的平均值及标准差，同时提供了用于制作论文图4与补充图S1的霍夫莫勒图（Hovmöller diagrams）所需的大西洋赤道断面与15°N断面的逐3小时数据。
文件名包含"geographical_mean"的文件为经纬度网格上的月平均数据；文件名包含"moisture_space"的文件为论文定义的热带大西洋湿空间内的月平均数据。
用于生成本数据集及开展论文所述分析的代码，已上传至软件章节所列的GitHub代码仓库中。
