ERA5 reanalysis data for total precipitation
收藏资源简介:
ERA5再分析数据集包含了全球范围内0.25◦×0.25◦分辨率、每小时时间分辨率的累计液态和固态降水量信息。论文选用阿尔卑斯山脉为中心的区域作为研究区域,对数据进行预处理后,使用RainScaleGAN模型进行降尺度处理。数据集由Copernicus Climate Data Store提供,经过滤波和特征缩放等预处理步骤,划分为训练集、验证集和测试集,以实现模型训练和评估。
The ERA5 reanalysis dataset contains cumulative liquid and solid precipitation data across the globe, with a spatial resolution of 0.25° × 0.25° and an hourly temporal resolution. This study selects the region centered on the Alps as the research area. After preprocessing the data, the RainScaleGAN model is employed for downscaling. The dataset is provided by the Copernicus Climate Data Store, and undergoes preprocessing steps including filtering and feature scaling before being split into training, validation and test sets for model training and evaluation.
