Dataset for Surrogate Model Benchmarking for Dynamic Climate Impact Models

The data represents time series of seasonal weather forecasts for rainfall and temperature. The dataset contains 10 forecasts of 6-month horizon from, two per year, from 2017 to 2021; start dates January 1 and July 1, respectively. Each forecast comprises 50 ensemble members. In total, this sums up to 91300 data points, each containing daily average rainfall, temperature. Each sample (row) comprises following features (columns): <strong>datetime</strong>: Date of the forecast sample. <strong>forecast</strong>: Identifier of the ensemble member, i.e. integer between 1 and total number of ensemblemembers. <strong>precip</strong>: Averaged daily rainfall forecast in millimeters. <strong>temp</strong>: Averaged daily temperature forecast in degree Celsius. Dataset created by The Weather Company, an IBM business. This service is based on data and products of the European Center for Medium-range Weather Forecasts (ECMWF-Archive and ECMWF-RT).

本数据集为降水与气温的季节数值预报时序数据。数据集包含2017年至2021年间的10组6个月时效的预报，每年发布2组，起始日期分别为每年1月1日与7月1日。每组预报包含50个集合成员（ensemble member）。总计包含91300条数据记录，每条记录涵盖逐日平均降水与气温数据。
每个样本（即表格行）包含以下特征（列字段）：
- **datetime**：预报样本的日期
- **forecast**：集合成员标识符，取值为1至总集合成员数之间的整数
- **precip**：以毫米为单位的逐日平均降水预报值
- **temp**：以摄氏度（℃）为单位的逐日平均气温预报值

本数据集由IBM旗下业务部门The Weather Company（天气公司）制作。该服务基于欧洲中期天气预报中心（European Center for Medium-range Weather Forecasts，ECMWF-Archive与ECMWF-RT）的数据及产品构建。本数据集利用哥白尼气候变化服务（Copernicus Climate Change Service）的相关信息生成（数据周期为2019年至今）。
